1. Introduction

Aviation passenger compensation claims in Thailand concern the legal rights of passengers who suffer financial loss, physical injury, baggage loss, flight delays, cancellations, denied boarding, or other harm arising from air transportation.

Thailand has developed a legal framework combining civil liability principles, international aviation conventions, consumer protection, and aviation regulatory rules.

The principal objective is to ensure that airlines fulfil their contractual obligations, provide reasonable passenger care, and compensate passengers when legally responsible for damage.

Aviation passenger compensation disputes generally involve:

Flight delays and missed connections.

Flight cancellations and refunds.

Denied boarding and overbooking.

Passenger injury and death.

Lost, delayed, or damaged baggage.

Disability-related passenger assistance.

Unfair airline contractual conditions.

Misrepresentation and failure to provide promised services.

Compensation for financial losses.

International passenger transportation disputes.

Important legal distinction: Thailand is a civil-law jurisdiction, and foreign judgments are not binding Thai precedents. There is also a comparatively limited body of publicly reported Thai aviation-compensation decisions. Accordingly, the six international decisions discussed below are identified as persuasive comparative authorities, not as Thai Supreme Court judgments.

2. Legal framework governing aviation passenger compensation

A. Civil and Commercial Code of Thailand

The Thai Civil and Commercial Code (CCC) establishes general contractual and carriage-related liability.

Particularly important provisions are:

Section 634 – Liability of passenger carriers

A passenger carrier is liable for:

Personal injuries suffered by passengers.

Damages immediately resulting from transportation delays.

The carrier may avoid liability where the injury or delay results from force majeure or the passenger's own fault.

This provision is particularly relevant to domestic passenger transportation claims and the general principles of carrier responsibility.

Section 635 – Delivery of luggage

Luggage entrusted to the carrier must be delivered when the passenger arrives.

Section 637 – Liability concerning entrusted luggage

The provisions governing carriage of goods also apply to entrusted passenger luggage.

Section 638 – Unchecked luggage

The carrier is generally not liable for luggage that has not been entrusted to it unless loss or damage results from the fault of the carrier or its employees.

Section 639 – Limitation of liability

Contractual provisions excluding or limiting carrier liability are subject to the statutory requirement concerning the passenger's express agreement.

These provisions establish an important foundation for passenger compensation litigation.

B. International Air Carriage Act B.E. 2558 (2015)

The International Air Carriage Act B.E. 2558 is one of Thailand's most important aviation compensation laws.

It implements the principles of the Montreal Convention 1999 into Thai law.

Its provisions regulate:

International passenger injury claims.

Passenger death claims.

Baggage destruction and loss.

Baggage damage.

Flight delay compensation.

Airline liability limitations.

Contributory negligence.

Limitation periods.

Domestic air carriage.

Important sections include:

Section 54 is particularly significant because it subjects claims arising from air carriage to the Act's conditions and liability limitations, regardless of whether the claimant describes the action as contractual or tortious. It also excludes punitive and other non-compensatory damages under the Act.

Section 55 establishes a two-year period for bringing an action, calculated according to the statutory rules.

C. Montreal Convention 1999

The Montreal Convention provides a uniform international framework for airline liability.

Its principal provisions include:

Article 17: Passenger death and bodily injury.

Article 19: Damage caused by delay.

Article 20: Passenger contributory negligence.

Article 21: Passenger death and injury liability.

Article 22: Limits of liability.

Article 29: Exclusivity of claims and exclusion of punitive damages.

Article 33: Jurisdiction.

Article 35: Two-year limitation period.

Thailand's International Air Carriage Act incorporates the Convention's principal liability framework.

The Convention is especially important for international journeys involving Thailand.

D. Civil Aviation Authority of Thailand (CAAT) Regulations

The Civil Aviation Authority of Thailand supervises airline passenger rights and compliance.

An important regulatory development is Regulation of the Civil Aviation Board No. 101, concerning passenger protection on domestic and international scheduled flights.

Effective 20 May 2025

The regulation covers:

Flight delays.

Flight cancellations.

Denied boarding due to overbooking or aircraft changes.

Passenger assistance.

Compensation and refunds.

Airline notification obligations.

It applies to Thai airlines operating domestic and international flights departing from Thailand and foreign airlines operating international flights departing from Thailand.

3. Major categories of aviation passenger compensation claims

A. Flight delay compensation claims

Flight delays are among the most common disputes between passengers and airlines.

A delay may result from:

Aircraft technical problems.

Airline scheduling failures.

Crew shortages.

Poor operational management.

Airport congestion.

Weather conditions.

Air traffic control restrictions.

Under Section 12 of the International Air Carriage Act, an airline may be liable for damage caused by delay unless it proves that it and its employees or agents took all measures reasonably required to avoid the damage, or that taking those measures was impossible.

Passengers may seek compensation for demonstrable losses such as:

Additional hotel expenses.

Additional transportation expenses.

Reasonable food and accommodation costs.

Financial losses arising from missed connections.

Other sufficiently established losses directly attributable to the delay.

Under CAAT Regulation No. 101, passengers also receive prescribed regulatory protections depending on the duration and circumstances of the delay.

The applicable regulatory rights should be distinguished from individual damages claims under the International Air Carriage Act.

B. Flight cancellation compensation claims

Flight cancellations may cause substantial inconvenience and financial losses.

Common disputes include:

Cancellation without sufficient notification.

Refusal to refund ticket payments.

Failure to provide alternative transportation.

Failure to arrange accommodation.

Cancellation shortly before departure.

Cancellation caused by airline operational problems.

Under Regulation No. 101, passengers are entitled to prescribed protection when covered flights are cancelled.

Depending on the circumstances, this can include:

Refund or alternative transportation.

Passenger care.

Statutory compensation.

Information about cancellation and available remedies.

A passenger should distinguish a refund of the ticket price from additional compensation for other legally recoverable losses.

C. Denied boarding and overbooking claims

Airlines sometimes sell more tickets than available seats.

When passengers arrive at the airport but are denied boarding, disputes can arise concerning the airline's contractual and regulatory obligations.

Relevant issues include:

Whether the passenger possessed a valid reservation.

Whether the passenger complied with check-in requirements.

Whether boarding was denied because of overbooking.

Whether the passenger voluntarily surrendered the seat.

Whether the airline offered alternative transportation.

Whether the passenger received the prescribed compensation.

Regulation No. 101 specifically addresses denied boarding caused by overbooking or aircraft changes.

The legal position must be distinguished from other forms of denied boarding covered by Regulation No. 104.

D. Passenger injury compensation claims

Passengers may suffer injuries during:

Aircraft turbulence.

Emergency landings.

Boarding and disembarking.

Aircraft evacuation.

In-flight accidents.

Cabin equipment failures.

Airline employee negligence.

Under Section 10 of the International Air Carriage Act, the carrier may be liable for death or bodily injury where the relevant accident occurs on board the aircraft or during embarking or disembarking operations.

The claimant must establish the applicable legal requirements, including the existence of an accident and the relevant injury.

Compensation may include legally recoverable medical expenses, loss of earnings, and other recognised consequences of bodily injury.

E. Passenger death compensation claims

Where a passenger dies because of an aviation accident, compensation claims may arise from:

The deceased passenger's estate.

Persons legally entitled to bring claims.

Dependants suffering recognised financial losses.

Persons entitled to compensation under applicable Thai succession and liability rules.

Relevant questions include:

Whether the death resulted from an aviation accident.

Whether the accident occurred within the relevant transportation period.

Whether the airline is legally responsible.

Whether contributory negligence applies.

Whether the claimant has legal standing.

Whether the claim complies with the applicable limitation period.

The Montreal Convention and Thai implementing legislation provide the primary framework for international carriage claims.

F. Lost and damaged baggage claims

Baggage disputes include:

Complete baggage disappearance.

Delayed baggage delivery.

Damage to suitcases.

Missing personal belongings.

Theft or disappearance of checked baggage.

Failure to deliver baggage at the destination.

Section 11 of the International Air Carriage Act establishes airline liability for destruction, loss, or damage to checked baggage in the circumstances covered by the Act.

An important provision concerns baggage that remains missing for 21 days after the date it should have arrived. The passenger can then enforce contractual rights against the carrier.

For international carriage, the Convention's baggage liability limits and notification requirements must also be considered.

G. Disability-related passenger compensation claims

Passengers with disabilities may encounter disputes involving:

Refusal of boarding.

Inadequate wheelchair assistance.

Unsafe passenger transfers.

Inaccessible aircraft facilities.

Failure to provide promised assistance.

Improper handling of mobility equipment.

The legal analysis may involve aviation regulations, contractual duties, applicable disability protections, and the Montreal Convention where the claim arises within its scope.

Not every service failure automatically creates a right to monetary damages. The nature, timing, and consequences of the alleged violation must be examined.

4. Six important case laws relevant to aviation passenger compensation

The following decisions are useful comparative authorities interpreting the Warsaw and Montreal Convention systems. They are not represented as judgments of Thai courts.

Case 1. Air France v. Saks (1985), 470 U.S. 392

Passenger bodily injury

Facts:

A passenger experienced severe ear pain during an aircraft's descent and subsequently suffered permanent hearing loss.

She argued that the airline was liable under the Warsaw Convention because an accident had occurred during the flight.

Legal issue:

What constitutes an accident under the international air carriage liability framework?

Judgment:

The United States Supreme Court explained that an accident involves an unexpected or unusual event external to the passenger, rather than the passenger's internal reaction to the normal operation of an aircraft.

Legal principle:

A bodily injury alone does not automatically establish airline liability. The claimant must establish the required causal connection between an external accident and the injury.

Relevance to Thailand:

This decision is particularly useful when interpreting Section 10 of Thailand's International Air Carriage Act and the meaning of an aviation accident.

Case 2. Olympic Airways v. Husain (2004), 540 U.S. 644

Airline negligence and passenger injury

Facts:

A passenger suffering from a serious respiratory condition repeatedly requested assistance to move away from cigarette smoke during an international flight.

The airline's personnel failed to provide the requested assistance. The passenger subsequently died.

Legal issue:

Could the airline's failure to respond to a passenger's requests constitute an accident under the Warsaw Convention?

Judgment:

The United States Supreme Court held that the airline employee's failure to act in the circumstances could constitute an unexpected or unusual external event.

Legal principle:

An airline's omission may qualify as an accident when the circumstances satisfy the applicable international liability test.

Relevance to Thailand:

This case is useful in disputes involving airline employees' failure to respond to foreseeable passenger safety risks, particularly where bodily injury or death occurs.

Case 3. Sidhu v. British Airways plc (1997), [1997] AC 430

International carrier liability

Facts:

Passengers brought claims against British Airways arising from circumstances involving international air transportation.

The dispute concerned whether passengers could pursue domestic legal remedies outside the liability framework of the Warsaw Convention.

Legal issue:

Can passengers avoid the international aviation liability framework by bringing claims under ordinary domestic law?

Judgment:

The House of Lords established that the Warsaw Convention provides an exclusive liability framework for claims falling within its scope.

Legal principle:

Where an international aviation claim is governed by the Convention, a claimant cannot simply avoid its requirements and limitations by relabelling the action as a domestic tort or contractual claim.

Relevance to Thailand:

The decision is especially relevant to Section 54 of Thailand's International Air Carriage Act, which subjects claims to the statutory liability framework regardless of the legal form in which they are brought.

Case 4. Morris v. KLM Royal Dutch Airlines (2002), [2002] UKHL 7

Psychological injury compensation

Facts:

A passenger brought a claim involving alleged sexual misconduct during an international flight and sought compensation for the resulting psychological consequences.

Legal issue:

Does psychological injury, without bodily injury, qualify as compensable bodily injury under the international air carriage regime?

Judgment:

The House of Lords concluded that psychological injury alone did not satisfy the bodily injury requirement under the Warsaw Convention.

Legal principle:

The distinction between bodily injury and psychological harm is important in determining whether a passenger's claim falls within the international aviation liability provisions.

Relevance to Thailand:

This decision provides guidance when assessing claims for emotional distress, humiliation, anxiety, and psychological injury arising during international air transportation.

Case 5. Stott v. Thomas Cook Tour Operators Ltd (2014), [2014] UKSC 15

Disability and passenger rights

Facts:

A passenger with disabilities experienced difficulties relating to seating and assistance during air transportation.

He sought damages for the treatment he received and the resulting distress.

Legal issue:

Could the passenger obtain damages under separate domestic disability legislation when the claim concerned matters within the scope of the Montreal Convention?

Judgment:

The UK Supreme Court applied the exclusivity principle of the Montreal Convention and rejected the damages claim in the circumstances.

Legal principle:

Claims arising within the scope of the Convention cannot ordinarily be used to circumvent its liability conditions through alternative domestic damages claims.

Relevance to Thailand:

This case is important for disputes involving disability assistance, airline service obligations, passenger treatment, and the relationship between aviation law and domestic civil remedies.

Case 6. Gahan v. Emirates (2017), [2017] EWCA Civ 1530

Flight delay compensation

Facts:

The litigation concerned airline passenger claims and the relationship between compensation under European passenger-rights legislation and the international air carriage liability regime.

Legal issue:

How should standardised passenger compensation rules be distinguished from claims for individual damages under the Montreal Convention?

Judgment:

The Court of Appeal considered the interaction between European passenger compensation rules and the Convention's limitations on individual damages claims.

Legal principle:

Standardised regulatory compensation and individual damages under international carriage law are legally distinct mechanisms. Their interaction depends on the applicable regulatory framework and the nature of the claim.

Relevance to Thailand:

This decision is useful when analysing the distinction between:

Prescribed compensation for flight disruption.

Refund and alternative transportation rights.

Individual financial losses.

Damages under Section 12 of Thailand's International Air Carriage Act.

The decision should not be treated as establishing that European Regulation 261/2004 applies to flights within Thailand.

5. Airline liability and available legal defences

Thai aviation law recognises that airline liability is not necessarily absolute.

Airlines may rely on several legal defences.

A. Force majeure

Under Section 634 of the Civil and Commercial Code, a carrier may avoid liability where the relevant injury or delay results from force majeure.

Examples may include:

Severe weather conditions.

Natural disasters.

Unexpected airport closures.

Certain security emergencies.

Extraordinary governmental restrictions.

However, ordinary operational difficulties do not automatically constitute force majeure.

B. Reasonable preventive measures

Under Section 12 of the International Air Carriage Act, an airline must demonstrate that it took all measures reasonably required to avoid the damage caused by delay, or that taking those measures was impossible.

An aircraft technical problem caused by inadequate maintenance, for example, may not provide a successful defence.

C. Passenger contributory negligence

Section 13 recognises contributory negligence.

Examples include:

Ignoring safety instructions.

Entering restricted aircraft areas.

Failing to follow crew instructions.

Passenger conduct contributing to an accident.

The airline's liability may be reduced or excluded to the extent permitted by the applicable statutory provisions.

D. Liability limitations

The International Air Carriage Act incorporates the Montreal Convention's liability limitation framework.

These limits differ according to whether the claim concerns passenger injury, delay, or baggage.

The applicable monetary limits must be checked against the relevant statutory amendments and Convention revisions applicable to the date of carriage.

E. Passenger documentation and contractual conditions

Airlines may rely on:

Conditions of carriage.

Electronic tickets.

Boarding passes.

Baggage receipts.

Passenger acknowledgements.

Contractual notices.

However, contractual terms cannot simply override mandatory statutory protections.

6. Procedure for filing aviation passenger compensation claims in Thailand

A passenger seeking compensation should follow a systematic legal procedure.

Step 1: Identify the responsible airline

Establish whether the claim concerns the operating carrier, contracting carrier, or another legally responsible party.

Step 2: Collect transportation documents

Preserve tickets, booking confirmations, boarding passes, baggage identification tags, and airline communications.

Step 3: Establish the nature of the violation

Identify whether the dispute concerns delay, cancellation, denied boarding, bodily injury, death, or baggage loss.

Step 4: Calculate the compensation

Identify the applicable regulatory entitlement, statutory liability limit, and actual financial loss.

Step 5: Submit a written claim to the airline

Include supporting documents, receipts, the incident description, and the requested remedy.

Step 6: Submit a complaint to CAAT

Where the airline fails to respect applicable passenger protections, passengers may use the CAAT complaint management system.

Step 7: Initiate court proceedings if necessary

A passenger may pursue the appropriate judicial remedy, subject to the relevant jurisdictional requirements and limitation periods.

The CAAT passenger complaint mechanism is available for alleged violations of applicable passenger-rights regulations.

7. Jurisdiction of Thai courts

The International Air Carriage Act contains specific jurisdictional provisions.

Under Section 58, domestic air carriage cases governed by the Act fall within the jurisdiction of the Intellectual Property and International Trade Court.

International carriage disputes must be assessed under the Act's jurisdictional provisions and the applicable international carriage rules.

Article 33 of the Montreal Convention also establishes the jurisdictions in which an international passenger claim may be brought.

The appropriate forum depends on:

The passenger's destination.

The airline's domicile.

The airline's principal place of business.

The place where the contract was made through an establishment of the carrier.

Any additional jurisdiction permitted under the Convention.

8. Limitation period for aviation passenger compensation claims

Limitation periods are particularly important because passengers can lose their right to pursue compensation if they fail to initiate proceedings within the prescribed period.

Section 55 of the International Air Carriage Act establishes a two-year period.

The period is calculated from the relevant statutory date, including:

The date of arrival at the destination.

The date on which the aircraft ought to have arrived.

The date on which the carriage stopped.

Article 35 of the Montreal Convention similarly establishes a two-year period for claims within its scope.

Passengers should not assume that submitting a complaint to an airline or CAAT automatically suspends or extends this period.

9. Important evidence in aviation passenger litigation

Successful compensation claims depend heavily on documentary evidence.

The claimant should also preserve records of alternative transportation and any additional costs caused by the airline's conduct.

10. Emerging legal challenges in Thailand

Aviation passenger compensation law is increasingly affected by technological and commercial developments.

A. Artificial intelligence and automated airline decisions

Airlines increasingly use automated systems for:

Passenger booking.

Flight scheduling.

Ticket cancellation.

Seat allocation.

Passenger risk assessment.

Refund processing.

Legal disputes may arise where automated systems incorrectly cancel bookings or deny boarding.

The principal questions include responsibility for automated decisions, contractual performance, negligence, and consumer protection.

B. Digital ticketing and electronic contracts

Electronic tickets create questions concerning:

Contract formation.

Passenger consent.

Electronic cancellation notices.

Digital evidence.

Unfair contractual terms.

Online refund procedures.

Thai electronic transaction legislation may also become relevant to these disputes.

C. Airline data breaches

Airline data breaches may expose:

Passport information.

Payment information.

Passenger contact details.

Travel histories.

Loyalty programme information.

Such claims may involve Thailand's Personal Data Protection Act B.E. 2562 (2019), alongside applicable contractual and civil liability rules.

D. Autonomous aviation systems

Future autonomous aircraft and automated flight-control technologies may create disputes involving:

Product liability.

Software failures.

Maintenance responsibility.

Aircraft operator negligence.

Passenger injury.

Insurance coverage.

These developments may require further legislative and judicial clarification.

E. Climate-related flight disruptions

Extreme weather and climate-related aviation interruptions may create difficult questions concerning:

Force majeure.

Airline operational responsibility.

Passenger care.

Refund obligations.

Compensation for missed connections.

The existence of adverse weather does not automatically eliminate every airline obligation.

11. Critical legal analysis

Thailand's aviation passenger compensation system has several strengths.

First, statutory protection: The Civil and Commercial Code provides a general foundation for passenger carrier liability.

Second, international harmonisation: The International Air Carriage Act incorporates important Montreal Convention principles, improving consistency in international aviation disputes.

Third, regulatory supervision: CAAT Regulation No. 101 provides more structured passenger protections for flight disruption.

Fourth, judicial remedies: Passengers can pursue appropriate court proceedings where airline conduct gives rise to legally recoverable claims.

However, certain difficulties remain.

Limited publicly available Thai aviation compensation case law makes the judicial interpretation of some liability questions less predictable.

Passengers may struggle to establish the actual financial consequences of delays.

The distinction between regulatory compensation and individual damages can create confusion.

International connecting-flight disputes can involve multiple airlines.

Passengers may not understand the two-year limitation period.

The interaction between domestic civil liability and international aviation conventions can complicate litigation.

A particularly important development would be clearer judicial guidance on airline responsibility for missed connections, automated booking failures, psychological injury, and technical maintenance failures.

12. Conclusion

Civil Law and Aviation Passenger Compensation Claims in Thailand represent an important intersection of contract law, tort liability, consumer protection, international aviation law, and administrative regulation.

The Civil and Commercial Code provides general principles of passenger carrier liability, while the International Air Carriage Act B.E. 2558 establishes the specialised framework for domestic and international air transportation claims.

CAAT Regulation No. 101, effective from 20 May 2025, strengthens regulatory protection against flight delays, cancellations, and certain forms of denied boarding.

The six comparative decisions—Air France v. Saks, Olympic Airways v. Husain, Sidhu v. British Airways, Morris v. KLM, Stott v. Thomas Cook, and Gahan v. Emirates—provide useful guidance concerning passenger injury, airline responsibility, international liability limitations, disability-related claims, and delay compensation.

Ultimately, effective passenger compensation requires a balance between airline operational responsibilities, passenger rights, international legal obligations, and fair civil remedies.

13. Important statutory and case-law revision points

Research qualification: The six cases are foreign comparative authorities, not six verified Thai aviation judgments. This distinction is important when using the material in a Thai law dissertation, academic article, or litigation memorandum.
