Alaska Airlines to Join American’s Joint Ventures: Who Wins?

Alaska Airlines is about to become a much bigger international player.
The Seattle based carrier plans to join American Airlines’ Atlantic and Pacific Joint Businesses, putting it alongside British Airways, Iberia, Finnair, Aer Lingus, LEVEL and Japan Airlines.
If regulators approve, it would be one of the most significant shifts in transatlantic and transpacific partnerships in years.
This analysis explains what is changing, why Alaska Airlines wants in and what it means for travellers on both sides of the Atlantic.
What Has Been Announced
Alaska Airlines announced on 29 September that American and Alaska intend for Alaska to join both joint businesses.
The Atlantic Joint Business was formed in 2010 and includes American, British Airways, Iberia, Finnair, Aer Lingus and LEVEL.
The Pacific Joint Business was launched shortly afterwards and brings together American and Japan Airlines.
Yahoo Finance reports that these arrangements allow partners to coordinate schedules, align pricing on selected routes and share revenue, once regulators approve them.
Nothing changes immediately.
Travel Market Report notes that the plan is subject to approval from the US Department of Justice and Department of Transportation, with filings for antitrust immunity expected in the coming months.
Why Joint Businesses Matter
Joint businesses go far beyond codesharing.
Partners effectively act as one airline on covered routes, sharing revenue and coordinating schedules so that flights complement rather than compete with each other.
That brings major advantages.
Airlines can offer more departure times, better connections and consistent fares across the partnership.
Antitrust immunity is essential.
Without it, competing airlines cannot legally coordinate pricing and capacity in this way, which is why regulators examine each application closely.
Why Alaska Airlines Wants In
Alaska has grown rapidly into an international airline.
Its merger with Hawaiian Airlines brought widebody aircraft and long haul routes, and the airline has been building a long haul network from Seattle.
Joining the joint businesses supports that strategy.
AirlineGeeks reports that Alaska chief commercial officer Andrew Harrison said joining would put Alaska on equal footing with its competitors.
Those competitors include Delta, which has its own joint ventures with Air France KLM, Virgin Atlantic and Korean Air, and United, which partners with Lufthansa Group and ANA.
Without a joint business, Alaska Airlines was at a disadvantage.
It could codeshare with oneworld partners, but could not coordinate fares and schedules in the same way as its biggest rivals.
How Alaska Airlines Has Changed
It is worth remembering how different Alaska Airlines looks today compared with a few years ago.
For most of its history it was a domestic airline focused on the West Coast, Alaska and Hawaii.
Joining oneworld in 2021 was the first major step towards a global role.
The acquisition of Hawaiian Airlines then added widebody aircraft, experienced long haul crews and a Pacific network.
Rus Tourism News notes that Alaska is now expanding its own Asian network from Seattle.
Becoming part of the joint businesses would allow those new routes to work alongside American, British Airways and Japan Airlines rather than in competition with them.
That combination of its own long haul flying and deep partnerships is exactly the model used by the largest US airlines.
Alaska Airlines is effectively moving into the same league.
What It Means for British Airways
British Airways stands to gain significantly on the Atlantic.
Travelling for Business notes that the plan would bring Alaska into partnership with British Airways, promising UK business travellers more connected West Coast itineraries.
Seattle and the wider Pacific Northwest are important markets for British Airways.
Alaska’s dense domestic network along the West Coast could feed far more passengers onto BA’s transatlantic flights.
International Airlines Group welcomed the plan.
Yahoo Finance reports that IAG chief commercial strategy officer Julio Rodríguez Contreras supported Alaska’s intent to join the Atlantic arrangement.
For UK travellers, the benefit is smoother journeys to cities such as Portland, Boise, Anchorage and smaller West Coast destinations, with a single coordinated product across BA and Alaska Airlines.
What It Means for Japan Airlines
The Pacific side is equally important.
Rus Tourism News notes that deeper cooperation with Japan Airlines comes as Alaska expands its own Asian network from Seattle.
Japan Airlines welcomed the move.
The Alaska announcement quotes JAL’s Ross Leggett, who noted that the airline is celebrating 15 years of its partnership with American.
For JAL, Alaska provides access to a large West Coast customer base.
For Alaska, JAL offers a gateway to Japan and onward connections across Asia.
What American Gains
American also benefits.
Its West Coast presence has long been weaker than that of Delta and United, and Alaska fills that gap.
AirlineGeeks reports that American chief commercial officer Nat Pieper described the move as building on a long standing partnership.
American and Alaska already offer reciprocal loyalty benefits and are both oneworld members.
Bringing Alaska into the joint businesses turns that partnership into something much closer to a combined network for international travel.
How Long Will It Take?
Travellers should not expect changes overnight.
Travel Market Report notes that the airlines plan to file for antitrust immunity and other approvals in the coming months, both in the United States and internationally.
Reviews of this kind often take many months.
Regulators will invite comments from rival airlines and other interested parties before reaching a decision.
Will Regulators Approve?
Approval is not guaranteed.
US regulators have become more cautious about airline partnerships in recent years, and the previous Northeast Alliance between American and JetBlue was blocked by a court.
However, international joint ventures with antitrust immunity have a long track record of approval, particularly where they compete with rival alliances.
The Atlantic and Pacific joint businesses already hold immunity.
Regulators will likely look closely at overlapping routes, especially on the West Coast and to Asia.
Conditions such as slot divestitures or capacity commitments are possible.
What It Means for Travellers With Alaska Airlines
For passengers, the potential benefits are clear.
More coordinated schedules, easier connections and consistent loyalty benefits across a larger network.
The risk is reduced competition on some routes.
When airlines share revenue, they have less incentive to undercut each other on price.
For Alaska Airlines frequent flyers, the move should broaden earning and redemption opportunities.
For British Airways and JAL customers, it opens up the West Coast in a more seamless way.

The Bottom Line for Alaska Airlines
Alaska Airlines joining American’s joint businesses would transform its international position.
It would sit alongside British Airways and Japan Airlines in two of the industry’s most powerful partnerships.
The deal still needs regulatory approval, but the strategic logic is strong.
For a carrier with growing global ambitions, this is a defining step.
