American moves to bring Alaska Airlines into Atlantic and Pacific joint businesses

American Airlines and Alaska Airlines plan to bring Alaska into American’s Atlantic and Pacific joint businesses, extending their international partnership across transatlantic and transpacific flying. The move, unveiled from Seattle and Fort Worth, is subject to regulatory approval and antitrust immunity before it can take effect.

If approved, Alaska would join American’s Atlantic joint business, which includes British Airways, Iberia, Finnair, Aer Lingus and LEVEL, as well as the Pacific joint business with Japan Airlines. The airlines expect to file for approval with the U.S. Department of Transportation and seek other international clearances in the coming months.

The arrangement would deepen coordination on schedules, pricing, network planning and revenue sharing on covered long-haul routes. It also gives Alaska a broader international platform while adding another U.S. carrier to American’s long-established overseas partnerships.

The Atlantic joint business dates to 2010, while the Pacific partnership was launched shortly afterwards, giving American a framework for coordinated service across major North Atlantic and transpacific markets. Alaska’s entry would expand that model to a wider customer base, though the operational change remains pending until regulators act.
