Airline Alliances and Market Coordination

1. Introduction

Airline alliances are cooperative arrangements between two or more airlines designed to improve network coverage, reduce operating costs, increase passenger convenience, and strengthen international connectivity. Airlines may cooperate through:

Code-sharing;

Joint marketing and advertising;

Coordinated schedules;

Frequent-flyer programme integration;

Reciprocal lounge and airport access;

Joint purchasing;

Revenue-sharing arrangements;

Joint ventures;

Coordinated capacity and route planning; and

In some cases, coordination of fares and inventory.

Examples of major global alliances include Star Alliance, oneworld, and SkyTeam. Alliances can create substantial efficiencies, but they may also reduce competition where independent airlines begin acting as a single economic entity.

The central competition-law question is:

Does the alliance merely improve connectivity and efficiency, or does it enable airlines to coordinate prices, capacity, routes, market allocation, or other competitive conditions?

2. Meaning of Market Coordination in the Airline Industry

Market coordination occurs when airlines align their commercial conduct instead of competing independently. Coordination may be:

A. Pro-competitive coordination

This may improve consumer welfare through:

More connecting flights;

Better use of aircraft and airport slots;

Lower operating costs;

Integrated ticketing;

Reduced travel time;

Better international connectivity;

More efficient use of capacity; and

Improved service quality.

B. Anti-competitive coordination

This may involve:

Fixing or coordinating airfares;

Agreeing on fuel or surcharge components;

Allocating routes or geographic markets;

Coordinating flight frequencies;

Limiting capacity;

Sharing commercially sensitive information;

Agreeing not to enter each other’s routes;

Coordinating baggage, cancellation, or ancillary charges; and

Excluding rival airlines from important distribution systems.

The same arrangement can contain both beneficial and harmful elements. Competition authorities therefore examine its actual structure, purpose, effects, and safeguards.

3. Forms of Airline Alliances

3.1 Code-sharing agreements

Under code-sharing, one airline markets a flight operated by another airline under its own flight code.

For example, Airline A may sell a ticket bearing its code even though Airline B operates the aircraft.

Possible benefits

Wider network coverage;

Easier connecting journeys;

Integrated reservations;

Better aircraft utilisation; and

Increased access to foreign markets.

Competition concerns

Code-sharing may become problematic where it:

Eliminates competition on overlapping routes;

Creates the appearance of multiple airlines while only one airline effectively controls the service;

Facilitates exchange of sensitive information;

Enables joint fare setting; or

Makes it difficult for consumers to compare alternatives.

A code-share on a connecting route is generally less problematic than a code-share between airlines that independently operate competing direct flights.

3.2 Interline agreements

Interline agreements permit passengers to purchase a single itinerary involving multiple airlines.

They usually involve:

Through-ticketing;

Baggage transfer;

Coordinated passenger handling; and

Revenue settlement between carriers.

These arrangements are usually efficiency-enhancing. However, they may raise concerns if the parties use the agreement to exclude rival airlines or impose discriminatory access conditions.

3.3 Frequent-flyer cooperation

Airlines may allow passengers to earn and redeem points across alliance members.

This can increase consumer choice, but a dominant airline may use its loyalty programme to:

Lock in corporate customers;

Offer rebates unavailable to rivals;

Make switching more difficult;

Tie domestic and international routes; or

Exclude smaller competitors from corporate travel contracts.

3.4 Joint ventures

A joint venture is a deeper form of cooperation in which airlines may coordinate:

Fares;

Schedules;

Capacity;

Revenue;

Sales;

Marketing; and

Network planning.

A joint venture may produce efficiencies similar to a merger. It may also remove rivalry between airlines that would otherwise compete on the same routes.

The closer the cooperation is to full commercial integration, the greater the need for competition-law scrutiny.

3.5 Global airline alliances

Global alliances connect airlines operating in different geographic markets. They may permit passengers to travel through a single integrated network.

Competition authorities generally distinguish between:

Cooperation on non-overlapping routes;

Cooperation on connecting routes;

Cooperation on overlapping direct routes; and

Full joint control over fares, schedules, and capacity.

The fourth category creates the greatest risk of market coordination.

4. Relevant Indian Competition-Law Framework

4.1 Section 3 of the Competition Act, 2002

Section 3 prohibits agreements that cause or are likely to cause an appreciable adverse effect on competition.

Section 3(3) is particularly relevant where airlines agree to:

Fix prices;

Limit or control production or supply;

Allocate markets or customers; or

Rig bids.

In the airline sector, “production or supply” may include the supply of:

Passenger seats;

Cargo capacity;

Flight frequencies; and

Route services.

An agreement to coordinate fares or limit available seats may therefore attract Section 3 scrutiny.

4.2 Section 3(4): Vertical restraints

Section 3(4) may apply to arrangements involving:

Exclusive distribution;

Exclusive supply;

Refusal to deal;

Tie-in arrangements; and

Other vertical restraints.

For example, an airline may use an exclusive travel-agent or online-distribution agreement to prevent rival airlines from accessing important booking channels.

4.3 Section 4: Abuse of dominant position

Section 4 becomes relevant where an airline or airline group holds a dominant position in a relevant market and engages in conduct such as:

Unfair or discriminatory pricing;

Predatory pricing;

Denial of market access;

Leveraging dominance from one route or airport to another;

Exclusionary loyalty rebates; or

Unfair conditions imposed on travel agents or passengers.

Dominance is not prohibited by itself. The prohibited conduct is abuse of dominance.

4.4 Relevant market

The relevant market may be defined by reference to:

City-pair routes;

Origin-and-destination combinations;

Domestic or international routes;

Business and leisure passengers;

Direct flights and connecting flights;

Airport catchment areas;

Cargo services; or

Airport-slot access.

The relevant market may differ depending on the facts. A passenger travelling from Delhi to London may not consider a Delhi–Mumbai flight a substitute. Similarly, a non-stop business traveller may not regard a connecting itinerary as an effective substitute.

5. Main Competition Concerns

5.1 Fare coordination

The most direct concern is coordination of airfares.

Airlines may exchange information or agree on:

Base fares;

Fuel surcharges;

Taxes and fees;

Baggage charges;

Cancellation fees;

Corporate discounts; or

Promotional pricing.

Even if the airlines do not expressly agree on a final ticket price, coordination of important price components may reduce competition.

5.2 Capacity coordination

Airlines may coordinate the number of seats offered on a route.

Capacity coordination can be anti-competitive when it is used to:

Reduce available seats;

Increase load factors artificially;

Raise fares;

Prevent new entry; or

Stabilise prices among alliance members.

Capacity cooperation may nevertheless be legitimate where it is necessary for a genuine integrated service, particularly on connecting routes.

5.3 Route and market allocation

Alliance members may agree that:

One airline will operate a particular route;

Another airline will avoid a competing route;

Certain airports will be reserved for particular members; or

Airlines will divide corporate or geographic customers.

Such arrangements may resemble market-sharing agreements and may attract serious competition-law scrutiny.

5.4 Exchange of commercially sensitive information

Airlines may exchange information about:

Future fares;

Seat inventory;

Planned capacity;

Flight cancellations;

Passenger demand;

Corporate contracts;

Revenue forecasts; and

Route-entry plans.

Information exchange becomes particularly problematic when it enables airlines to predict and align their competitive behaviour.

Information sharing should therefore be limited to what is objectively necessary for the alliance and should include safeguards against the circulation of competitively sensitive data.

5.5 Slot concentration

Airport slots are often scarce. An alliance may control a large proportion of slots at a congested airport.

This may create:

Barriers to entry;

Higher switching costs;

Reduced access for new airlines;

Coordinated dominance over particular routes; and

Strategic exclusion of rivals.

A competition authority may require slot divestiture, access commitments, or restrictions on the use of certain slots.

5.6 Loyalty-programme foreclosure

Integrated frequent-flyer programmes may create network effects. The more routes and partners a programme has, the more valuable it becomes.

A dominant alliance may use this advantage to:

Lock in business travellers;

Offer preferential corporate contracts;

Make rival airlines less attractive;

Condition rebates on exclusive purchasing; or

Bundle international and domestic services.

The issue is whether the loyalty programme rewards genuine consumer loyalty or improperly forecloses competing airlines.

5.7 Predatory pricing

An airline or alliance may temporarily price below cost to eliminate a rival and later increase fares.

Predatory pricing is difficult to establish because airlines often have:

High fixed costs;

Low marginal costs;

Seasonal demand;

Perishable inventory; and

Legitimate reasons for discounting unsold seats.

The authority must distinguish ordinary yield management from a deliberate strategy to exclude competitors.

5.8 Dynamic pricing and algorithmic coordination

Airlines use sophisticated revenue-management systems to adjust fares based on:

Demand;

Booking time;

Remaining inventory;

Competitor prices;

Passenger type;

Seasonality; and

Route conditions.

Dynamic pricing is not automatically unlawful. It becomes problematic if airlines:

Use a common pricing algorithm;

Share future pricing intentions;

Coordinate through a third-party platform;

Use algorithms to implement an underlying agreement; or

Deliberately design systems to avoid independent competition.

6. Case Laws

Case 1: European Commission v. Air France-KLM and Alitalia-related airline cooperation

European airline cases concerning cooperation between major carriers demonstrate that alliances must be assessed by reference to the routes on which the parties compete.

Principle

Cooperation may be acceptable on routes where the parties do not compete, but it may be problematic where the arrangement removes rivalry on overlapping city-pair routes.

Relevance

The case law shows that competition authorities examine:

Overlapping routes;

Passenger substitutability;

Frequency of flights;

Airport presence;

Business and leisure passengers;

Network effects; and

Whether competitors can realistically replace the parties.

The key lesson is that an alliance cannot be justified merely by describing itself as an efficiency-enhancing partnership.

Case 2: European Commission v. Lufthansa and Austrian Airlines

The Lufthansa–Austrian Airlines transaction was examined in the context of overlapping routes and the parties’ strong position at important airports.

Principle

A combination of network carriers may create substantial market power where the airlines operate from dominant hubs and control important city-pair routes.

Competition concerns

The authority considered issues such as:

Dominance at hub airports;

Overlapping routes;

Reduced frequency competition;

Barriers to entry; and

The ability of rival airlines to obtain airport slots.

Relevance

The case illustrates that airport concentration and route overlap must be assessed together. Even where several airlines formally remain in the market, competition may be weakened if alliance members control the principal hub, slots, and connecting traffic.

Case 3: European Commission v. Air France and KLM

The Air France–KLM combination is an important example of the competition assessment of airline network integration.

Principle

The relevant inquiry is not limited to whether the parties compete on a single route. Authorities also examine:

The parties’ combined network;

Hub dominance;

Connecting traffic;

Corporate customers;

Airport access; and

The possibility of entry by rival carriers.

Relevance

The case demonstrates that airline market power can arise from network advantages rather than only from a high market share on one individual route.

An alliance may be particularly powerful where it offers:

More destinations;

Better connections;

Greater schedule frequency;

Integrated loyalty benefits; and

Corporate travel agreements.

Case 4: United States v. American Airlines Group and US Airways Group

The proposed American Airlines–US Airways merger was challenged by the United States Department of Justice.

Principle

The merger raised concerns that reducing the number of major airlines could increase fares, reduce service, and weaken competition at important airports.

Relevant issues

The case involved:

Concentration in the airline industry;

Competition on overlapping routes;

Airport slots;

Network effects;

Entry barriers; and

The effect of consolidation on consumers.

Relevance to alliances

Although a merger is different from an alliance, a deeply integrated alliance may produce similar competitive consequences where the parties coordinate fares, schedules, capacity, and sales.

The case therefore supports the proposition that airline cooperation must be examined for its practical economic effect rather than its contractual label.

Case 5: United States v. Delta Air Lines and Northwest Airlines

The Delta–Northwest merger was examined against the background of airline consolidation and network competition.

Principle

The case illustrates the importance of:

Hub concentration;

Route overlap;

Airport access;

Consumer choice;

Network connectivity; and

The ability of smaller airlines to discipline the merged firm.

Relevance

An alliance may increase market power if it allows members to combine hub advantages while continuing to present themselves as separate airlines.

Competition authorities may therefore ask whether the alliance creates a “virtual merger” on particular routes.

Case 6: United States v. Airline Tariff Publishing Company

The Airline Tariff Publishing Company litigation concerned the use of a computerised fare-publication system by airlines.

Principle

Publicly communicating fares is not automatically unlawful. However, an information system may facilitate collusion where airlines use it to:

Signal future price changes;

Coordinate fare increases;

Monitor compliance;

Delay competitive responses; or

Communicate intentions through fare announcements.

Relevance

This case is especially important for modern airline pricing systems. Digital platforms and algorithms can facilitate coordination even without a traditional face-to-face meeting.

The legal question is whether the technology merely publishes independent prices or becomes a mechanism for coordinated conduct.

Case 7: Eturas UAB v. Lietuvos Respublikos konkurencijos taryba, Case C-74/14

In Eturas, the Court of Justice of the European Union considered an online booking platform that communicated a common restriction on discounts to travel agencies.

Principle

A common electronic system may facilitate anti-competitive coordination. Participation in the system, combined with knowledge of the communicated restriction and failure to distance oneself from it, may support an inference of involvement.

Relevance to airlines

The principle may apply where airlines use:

A common reservation platform;

A shared pricing system;

A common commission structure;

A joint distribution tool; or

A platform that restricts discounts.

The case shows that coordination can occur through digital infrastructure and need not always take the form of a traditional written agreement.

Case 8: BIDS v. Commission, Case C-209/07

The BIDS case concerned cooperation among meat processors designed to reduce production capacity.

Principle

An arrangement aimed at removing excess capacity and stabilising prices may restrict competition by object.

Relevance to airlines

The analogy is significant because airlines may attempt to justify coordinated capacity reductions as necessary to improve efficiency or prevent destructive competition.

However, if the real objective is to remove seats from the market and increase prices, the arrangement may be treated as a serious restriction of competition.

Case 9: Competition Commission of India v. Steel Authority of India Ltd.

The Supreme Court of India explained important principles concerning the Competition Act and the role of the Competition Commission of India.

Principle

The Competition Act is concerned with protecting the competitive process and consumer welfare. The CCI must examine the statutory requirements before proceeding against an enterprise.

Relevance to airlines

In an airline matter, the CCI would need to examine:

The relevant market;

The nature of the agreement;

Whether the parties are competitors;

Whether the conduct has an appreciable adverse effect on competition;

Whether an enterprise is dominant; and

Whether the alleged conduct falls within Sections 3 or 4.

The case is useful for understanding the institutional and analytical framework of Indian competition enforcement.

Case 10: CCI v. Bharti Airtel Ltd.

The Supreme Court considered the relationship between sectoral regulation and competition law.

Principle

Competition law may operate alongside sector-specific regulation, but the proper regulatory sequence and institutional competence must be respected.

Relevance to airlines

The airline sector is regulated by aviation authorities concerning:

Safety;

Slots;

Airport operations;

Route permissions;

Consumer protection; and

Air-service arrangements.

However, aviation regulation does not automatically immunise airlines from competition law. Conduct involving fare coordination, market allocation, or exclusionary practices may still require competition analysis.

7. Assessment of an Airline Alliance

A competition authority may examine the following factors.

7.1 Market shares

Relevant questions include:

What are the parties’ combined shares on affected routes?

Do they control a major hub?

How many credible competitors remain?

Are low-cost carriers effective substitutes?

Are there barriers to obtaining slots?

Market share is important but not conclusive.

7.2 Route overlap

The authority will distinguish between:

Non-overlapping routes;

Routes with indirect competition;

Routes with competing direct flights; and

Routes where the alliance becomes the only effective supplier.

The greatest concern arises where the alliance removes the only meaningful competitor.

7.3 Hub dominance

An airline may possess significant power because it controls a hub airport.

Hub dominance may allow the airline to:

Coordinate connecting traffic;

Control departure times;

Restrict rivals’ access to slots;

Offer a superior loyalty programme; and

Increase switching costs for passengers.

7.4 Entry barriers

Airline entry may be difficult because of:

Scarce airport slots;

High aircraft costs;

Regulatory permissions;

Airport infrastructure;

Brand loyalty;

Frequent-flyer networks;

Corporate contracts; and

Limited access to profitable routes.

Where entry is difficult, even a moderate alliance may produce substantial market power.

7.5 Countervailing buyer power

Large corporate customers, travel-management companies, and online travel agencies may exercise some bargaining power.

However, their power may be limited where:

The alliance controls essential routes;

Corporate travellers require frequent schedules;

Alternatives involve inconvenient connections; or

Loyalty benefits discourage switching.

8. Possible Defences and Efficiencies

Airlines may argue that the alliance produces:

New routes;

Better connections;

Lower costs;

Increased flight frequency;

Improved aircraft utilisation;

Better consumer choice;

Lower fares on connecting itineraries;

Enhanced service quality; and

Greater international competitiveness.

These efficiencies must be:

Verifiable;

Specific to the alliance;

Likely to benefit consumers; and

Sufficient to offset the harm to competition.

A general claim that “the alliance improves efficiency” is not enough. The parties should show how the claimed efficiencies arise and how consumers will receive the benefit.

9. Possible Remedies

Competition authorities may impose remedies such as:

Surrender of airport slots;

Access to reservation systems;

Prohibition on certain fare coordination;

Restrictions on exchange of sensitive information;

Independent pricing requirements;

Ban on exclusive corporate contracts;

Requirement to maintain separate sales teams;

Monitoring of capacity commitments;

Appointment of an independent trustee; and

Periodic review of the alliance.

In serious cases, authorities may prohibit the arrangement or require structural separation.

10. Compliance Guidelines for Airlines

Airlines participating in an alliance should:

Define the exact scope of cooperation;

Avoid unnecessary exchange of future pricing information;

Maintain independent pricing where required;

Create information barriers;

Document the efficiency rationale;

Conduct route-by-route competition assessments;

Review slot and airport concentration;

Avoid agreements allocating customers or routes;

Train employees on competition law;

Monitor communications with alliance partners;

Obtain legal review before expanding cooperation; and

Preserve records demonstrating independent decision-making.

The alliance agreement should clearly distinguish permissible operational cooperation from prohibited coordination of competitive variables.

11. Conclusion

Airline alliances occupy an important position between ordinary commercial cooperation and merger-like integration. They can create major benefits through network expansion, integrated ticketing, improved connectivity, and cost savings. However, they may also facilitate coordination of fares, capacity, routes, schedules, customer allocation, and commercially sensitive information.

Under Indian competition law, the principal provisions are Sections 3 and 4 of the Competition Act, 2002. Section 3 addresses anti-competitive agreements, while Section 4 addresses abuse of dominance. The analysis depends on the relevant route market, the degree of integration, hub and slot concentration, the availability of substitutes, and the actual effects on consumers.

The essential principle is:

An airline alliance is lawful when it produces genuine efficiencies without eliminating independent competition; it becomes problematic when cooperation is used to coordinate market behaviour or exclude rivals.
