American and Alaska Airlines Move to Expand Revenue-Sharing Pacts
American Airlines Group and Alaska Air Group are taking a major step toward deeper cooperation, announcing plans for Alaska Airlines to join American Airlines’ Atlantic and Pacific Joint Businesses.
The proposed expansion would extend an existing partnership between the two U.S. carriers into American’s major international revenue-sharing arrangements, connecting Alaska’s growing West Coast network with long-haul operations involving British Airways, Iberia, Finnair, Aer Lingus, LEVEL and Japan Airlines.
The airlines said they expect to seek approval and antitrust immunity from the U.S. Department of Transportation, along with relevant approvals from international regulators, in the coming months.
For investors, the development matters because Alaska is trying to accelerate its transformation from a primarily West Coast carrier into a broader international airline, while American gains deeper access to Alaska’s network and customer base without having to build the entire network itself.
What American and Alaska Are Planning
Under the proposed arrangement, Alaska Airlines would join two existing international joint businesses operated with American.
The Atlantic Joint Business, established in 2010, currently includes American, British Airways, Iberia, Finnair, Aer Lingus and LEVEL. The group coordinates elements of its transatlantic operations and shares revenue across the joint business.
The Pacific Joint Business consists of American Airlines and Japan Airlines. The partnership has operated for about 15 years and focuses on connectivity between North America and Asia.
Alaska's proposed entry would bring its West Coast network into both arrangements. The company said the move would give customers more seamless access to international destinations while strengthening its competitive position.
The plan is not a merger. American and Alaska would remain separate airlines, but would have substantially deeper cooperation in the international markets covered by the joint businesses.
Why Alaska Wants Deeper International Partnerships
The move fits directly into Alaska Air Group's broader Alaska Accelerate strategy.
Alaska has been expanding its international reach following its acquisition of Hawaiian Airlines, while also using the oneworld alliance to connect customers to a much larger global network.
The company's current network includes hubs in Seattle, Honolulu, Portland, Anchorage, Los Angeles, San Diego and San Francisco. Alaska and Hawaiian are both members of oneworld, whose participating airlines collectively provide access to more than 1,100 destinations through Alaska's loyalty and partner network.
Joining American's joint businesses would go beyond a conventional codeshare relationship.
A codeshare generally allows one airline to sell seats operated by another carrier. A joint business can involve much deeper coordination, including route planning, capacity and schedules, pricing, inventory and corporate sales.
That distinction is important because it can allow airlines to manage a network more like a single commercial operation while continuing to operate separate aircraft and brands.
What American Gains From the Deal
American already has a long-standing relationship with Alaska through codesharing, loyalty benefits and the oneworld alliance.
American's 2025 annual report describes Alaska as a strategic alliance partner and says the relationship provides customers with an improved network and reciprocal loyalty benefits.
The proposed expansion could make that relationship significantly more valuable.
Alaska has a particularly strong position on the U.S. West Coast, while American operates a much larger global network. Combining the two commercially could create more connecting opportunities for passengers traveling between smaller West Coast markets and destinations in Europe and Asia.
For American, this potentially improves the reach of its international partnerships without requiring the carrier to operate every connecting route itself.
For Alaska, it provides a way to feed more passengers into international services operated by American and its partners.
Why Revenue Sharing Matters
Revenue-sharing agreements are designed to align the economic interests of participating airlines.
Instead of each carrier treating every connecting passenger as a separate transaction, joint-business partners can coordinate routes, fares and capacity and then share revenue generated by the combined network.
This can be particularly useful for long-haul markets, where operating an aircraft is expensive and profitability depends heavily on filling seats with the right mix of passengers.
A West Coast passenger flying from a smaller U.S. city to Europe, for example, could travel on Alaska for part of the journey and connect to an American or European partner flight. A deeper joint business can make that itinerary commercially easier to coordinate.
The potential benefit is not simply more destinations on a route map. It is the ability to extract more value from an existing network.
The Regulatory Hurdle Is Still Significant
The announcement does not mean the expanded partnership has been approved.
American and Alaska said they expect to submit applications for approval and antitrust immunity to the U.S. Department of Transportation in the coming months. Other international regulatory approvals may also be required.
Antitrust immunity is particularly important because joint businesses can allow airlines to coordinate commercial decisions that competitors would normally make independently.
U.S. regulators have previously scrutinized airline partnerships. American's former Northeast Alliance with JetBlue, for example, became the subject of a major antitrust case and was ultimately terminated after litigation.
That history means investors should distinguish between the airlines announcing their intention to pursue the arrangement and regulators actually approving it.
The timing and final terms therefore remain uncertain.
Alaska's Broader International Expansion
The proposed partnerships come as Alaska is simultaneously investing in a more international business model.
At its recent investor presentation, Alaska said it plans to expand Seattle service to at least 15 intercontinental destinations by 2030. The company also expects premium revenue to exceed 40% of total revenue by 2030, compared with about 35% currently, according to its investor materials.
Alaska has also been emphasizing premium cabins, lounges and loyalty economics as part of its broader strategy.
The carrier recently said it expects premium revenue to become more than 40% of total revenue by 2030, while its broader premium and international strategy is intended to increase the value generated from customers willing to spend more on long-haul travel.
The deeper American partnership therefore fits into a larger effort rather than representing an isolated commercial agreement.
What It Could Mean for American Airlines and Alaska Air Stocks
For American Airlines (NASDAQ: AAL), the potential benefit is primarily network-related. A stronger Alaska relationship could improve access to West Coast traffic and strengthen American's international joint businesses.
For Alaska Air Group (NYSE: ALK), the potential impact is more structural. Alaska is trying to build a larger international presence while integrating Hawaiian Airlines and increasing the proportion of revenue coming from premium customers and diversified businesses.
However, investors should not automatically translate the announcement into higher earnings.
The partnership still requires regulatory approval, and the financial benefits will depend on passenger demand, route economics, capacity decisions, fuel prices and the ability of the carriers to execute the expanded network.
Alaska also remains exposed to the cost pressures affecting the wider airline industry. The company recently highlighted fuel prices as a major near-term earnings variable, illustrating why stronger network economics alone cannot remove the industry's cost risks.
What Investors Should Watch Next
The next major catalyst is the regulatory filing.
Investors should monitor:
The timing and details of the DOT applications.
Whether antitrust immunity is granted.
Any conditions imposed by U.S. or international regulators.
Changes to American and Alaska route planning.
Growth in West Coast international connectivity.
Passenger and premium-revenue trends at Alaska.
Integration progress following the Hawaiian Airlines acquisition.
Fuel prices and their effect on airline profitability.
Whether the expanded partnership produces measurable improvements in revenue and network utilization.
The commercial logic is clear: American brings scale and established international joint businesses, while Alaska contributes a strong West Coast network and its expanding Hawaiian operation. The financial outcome, however, will depend on regulatory approval and execution.
Conclusion
American Airlines and Alaska Airlines are moving to deepen their partnership by bringing Alaska into American's Atlantic and Pacific Joint Businesses. The proposed arrangement would connect Alaska's West Coast network more closely with American's European and Japan Airlines partnerships and could give Alaska a larger role in international travel.
For investors, the important point is that this is part of Alaska's broader strategy to build a more global airline rather than simply a new codeshare agreement. The next key developments will be the regulatory filings, antitrust-immunity decisions and evidence that the expanded network is translating into stronger revenue and premium demand.
