Alaska Airlines is extending its long-standing Seattle rivalry with Delta Air Lines to new international routes, using widebody aircraft acquired through its merger with Hawaiian Airlines to target premium long-haul travelers.
Throughout much of its history, Alaska generated steady profits by keeping operating costs below those of major US network carriers while building customer loyalty across the Pacific Northwest with a primary focus on domestic routes.
Based in a corporate hub shared by Amazon, Microsoft, Starbucks, Costco, and major Boeing manufacturing facilities, the airline now aims to increase earnings from premium cabins, international flights, and its loyalty program, all while retaining its underlying cost advantage.
Alaska plans to triple its intercontinental routes out of Seattle to at least 15 by 2030, positioning itself as the city’s primary international carrier. Scheduled service launches for next year include flights to Paris and Athens.
Reuters analyzed Cirium schedule data and found that roughly 92% of Alaska’s planned intercontinental seats from Seattle through August 2027 directly overlap with nonstop routes already operated by Delta, placing nearly all of its new capacity in head-to-head competition with its larger rival.
The pivot is a strategic bet that growing premium and long-haul international revenue can bridge a financial margin gap with larger competitors that lower operating expenses alone cannot close.
During the first half of the year, Alaska spent about 17% less per seat mile (excluding fuel) than the combined average of Delta, United Airlines, and American Airlines, according to a Reuters analysis of financial filings. However, it generated roughly 20% less revenue per seat mile, leaving less margin to absorb fuel price spikes linked to conflict in Iran.
“The airlines that actually have high cost structures are the ones making the highest margins,” Alaska CEO Ben Minicucci told investors on Tuesday. “We need to pivot.”
The escalating battle at the third-busiest airport on the US West Coast mirrors a broader industry effort to capture premium, international, and loyalty-based revenue, which has become a crucial profit driver for major US airlines. A similar competitive clash between American and United is currently playing out at Chicago O’Hare.
Delta, which regards Seattle as its primary Pacific hub, added flights to Rome this summer and plans a daily service to Tokyo Narita in March 2027—a route Alaska currently operates. Delta has also secured preferential access to 18 airport gates alongside opening two additional lounges.
For Alaska, the competitive stakes are significant as higher fuel prices have weighed on profits this year.
The carrier estimates that international travel generates approximately 30% of total passenger revenue in Seattle, a market segment it previously captured only in part.
To build Seattle into a long-haul gateway to Europe and Asia, Alaska is introducing Boeing 787s, expanding premium seating options, and constructing new airport lounges.
Alaska announced on Tuesday that it intends to join American Airlines’ revenue-sharing joint ventures across the Atlantic and Pacific oceans. Subject to regulatory approvals and antitrust immunity, the arrangement would allow the airlines to align schedules and fares while sharing revenue on covered international routes.
The strategy focuses on Alaska’s primary hub, where Delta has built a competing base. The two airlines ended their codeshare and frequent-flier partnership in 2017 as competition intensified.
Together with Hawaiian Airlines, Alaska controls roughly half of all scheduled seats in the Seattle market—double Delta’s current share. Overseas, however, the balance flips: Delta holds nearly double Alaska’s intercontinental seat capacity out of Seattle over the same timeframe, according to Cirium data.
Alaska intends to leverage its domestic market position to feed passengers from across the Western US onto its international flights.
More than half of passengers on Alaska’s flights to Seoul and Reykjavik connect through Seattle, the airline told Reuters, whereas routes to London and Rome rely more on direct local traffic. In an interview, President and Chief Financial Officer Shane Tackett said connecting traffic has run above expectations on some long-haul routes.
Delta did not respond to Reuters’ request for comment.
Expanding internationally brings added fleet, staffing, and operational complexities, while increasing direct conflict with Delta. The central risk is that operating costs could escalate faster than the incoming revenue required to offset them.
Melius Research analyst Conor Cunningham noted that while Alaska is targeting logical growth areas, it faces short-term pressures from elevated fuel prices and intense competition in primary markets.
The airline has minimal room for strategic missteps, expecting to end 2026 with net leverage—debt relative to earnings—at three times its long-term target.
Alaska’s Boeing 787 operations are experiencing higher-than-normal crew costs as it establishes pilot and flight attendant bases in Seattle. Tackett said these expenses should normalize as additional aircraft arrive and the operation gains scale.
Its initial European summer illustrated how quickly route economics can shift. Stronger-than-expected premium seat demand to London pushed the route into profitability in July before rising fuel expenses erased those gains, Tackett said.
By 2030, Alaska projects that nearly 60% of its total revenue will come from options outside the standard main cabin, up from 53% this year, a transition it believes will strengthen business resilience.
“What we’ve recognized is the winning airline of the future looks different than it did 10 years ago,” Tackett told Reuters.
