Alaska Airlines to Launch Seattle-Paris and Seattle-Athens Routes in May 2027

en.Wedoany.com Reported - Alaska Airlines announced it will launch nonstop flights from Seattle-Tacoma International Airport (SEA) to Athens, Greece, and Paris, France, starting next May, with both routes operated by Boeing 787-9 aircraft on a seasonal basis through October. The move marks an acceleration of the carrier's transformation from a regional airline into a global one.

With this announcement, Alaska Airlines will have five European destinations from Seattle, just over a year after its first transatlantic route—to Rome—launched in April 2025. However, rapid expansion brings two major challenges: the Paris route will put it directly into a market long operated by rival Delta Air Lines; meanwhile, the new routes put pressure on Boeing 787 Dreamliner delivery schedules and crew staffing, with pilots reporting shortages on long-haul flights.

Athens to Become the Longest Route in Alaska Airlines History

Athens' Eleftherios Venizelos International Airport (ATH) is the more pioneering destination of the two new routes. At 6,197 miles (9,972 kilometers), the Seattle-Athens route will become the longest in Alaska Airlines' operating history. The company said this will be the first nonstop Seattle-Athens flight and the only direct connection between the Greek capital and the U.S. West Coast. The three-times-weekly frequency reflects the highly seasonal nature of Greek leisure travel demand; Alaska's extensive connecting network in Seattle should help attract travelers from across the western United States, Alaska, and Hawaii.

The situation at Paris Charles de Gaulle Airport (CDG) is different. Alaska will enter a mature market, as Delta Air Lines and its joint venture partner Air France already operate Seattle-CDG service with up to 12 weekly flights. Alaska's launch frequency of five weekly flights, rather than three, signals expectations of significantly stronger demand. CEO Ben Minicucci noted that Paris is already one of the most-searched destinations on alaskaair.com: "We fly where our guests want to go, and Athens and Paris have been at the top of that list for years."

The two new routes build on a European network that barely existed 16 months ago. Rome's Fiumicino Airport (FCO) opened Alaska Airlines' European era in April 2025, followed by London Heathrow Airport (LHR) in May, and Reykjavik later that same month. Currently, London is the only year-round European route; the Reykjavik service uses the smaller Boeing 737 MAX 8 rather than one of Alaska's scarce Dreamliners. By summer 2027, Alaska will have seven intercontinental destinations from Seattle, including existing routes to Tokyo Narita Airport (NRT) and Seoul Incheon International Airport (ICN), with plans to add at least five more by 2030.

The Battle for Seattle Goes Global

Alaska Airlines and Delta Air Lines were once close partners in Seattle. In 2012, Delta said Alaska's domestic network was a key driver for expanding its international gateway, with Alaska feeding passengers to Delta flights to destinations such as Amsterdam, Paris, and Tokyo. But Delta gradually built its own domestic network at Seattle-Tacoma International Airport, reducing its reliance on Alaska, and the two carriers found themselves in direct competition. Relations deteriorated before their codeshare and frequent flyer partnership ended in 2017.

Nearly a decade later, that competition has gone global. By summer 2027, of Alaska Airlines' seven intercontinental destinations from Seattle, five will also be served nonstop by Delta: London, Paris, Rome, Seoul, and Tokyo Narita. Alaska will use the 787-9 in all five markets, while Delta primarily deploys the Airbus A330-900 on European and Narita routes and the larger Airbus A350-900 on the Seoul route.

Route overlap is escalating rapidly, with recent route announcements increasingly resembling a series of tit-for-tat moves. Alaska entered Delta's mature Seoul and London markets, Delta responded by following Alaska into Rome, and Delta recently announced it will return to Narita in March 2027. Alaska's new Paris route brings the fight into yet another market long dominated by Delta and a core hub of the SkyTeam alliance.

The stakes are particularly high because the two carriers have different strengths. In 2025, Alaska Air Group carried 50.7% of all passengers at Seattle-Tacoma International Airport—more than double Delta's 24.1%—giving it a large local customer base and connecting traffic to feed its new 787 operations. However, when it comes to international passengers, the picture is reversed: Delta accounts for 24.8% of SEA's international travelers, while Alaska holds just 14.7%. Alaska's long-haul expansion can be seen as an attempt to convert its overwhelming overall dominance in Seattle into international market share, while Delta is increasingly deploying its much larger long-haul fleet resources precisely to prevent that from happening.

Alaska Airlines Needs Its Dreamliner Deliveries

While Alaska holds the home-field advantage, Delta has a significant edge in fleet depth. Delta operates more than 180 widebody aircraft spanning the A330, A350, and Boeing 767 families, with dozens of A330s, A350s, and Boeing 787-10s on order. Alaska Air Group does own 24 Airbus A330-200s (from Hawaiian Airlines), but those aircraft will remain centered on Honolulu; Alaska has explicitly designated Seattle as its Dreamliner hub. Its Seattle global network expansion therefore depends particularly on 787 delivery schedules.

In the near term, 787 deliveries remain limited. Alaska had five 787-9s at the end of 2025, expects its sixth by the end of 2026, and its seventh in 2027. Subsequently, four larger 787-10s are scheduled for delivery in 2028, bringing the Dreamliner fleet to 11. Alaska has directly acknowledged this risk in its annual report, noting that Boeing's production constraints have affected 787 deliveries and warning that its smaller size means delivery delays could have a disproportionate impact on its growth.

This could make summer 2027 particularly demanding: Alaska may need to cover Tokyo, Seoul, London, Rome, Paris, and Athens with its modest Dreamliner fleet, with little of the redundancy Delta enjoys. Longer term, Alaska already has enough firm orders to bring its Dreamliner total to 17, including five planned 787-10s. If its goal of at least 12 Seattle long-haul destinations is just the beginning, a next widebody order seems inevitable.
