Alaska Airlines plans to begin nonstop service from Seattle-Tacoma International Airport to Guadalajara on March 18, 2027, according to Simple Flying. The airline expects to fly the route year-round, up to three times weekly, using Boeing 737-800 aircraft. The planned flights would give Seattle travelers another nonstop option to Guadalajara, but the schedule and launch are still in the future.
A route with established competition
Alaska would join Volaris and Aeromexico on the Seattle–Guadalajara nonstop route, Simple Flying reports. Volaris’s presence dates to 2016: the Port of Seattle said the carrier announced three weekly nonstop flights beginning July 7 that year. Simple Flying reports that Aeromexico began serving the city pair in 2025. The Port’s record documents Volaris’s earlier launch, but does not establish how frequently either competitor flies today.
The Port of Seattle reported that outbound travel from SEA to Mexico in 2024 was 101% above 2019 levels. That broad airport figure offers context for the new service, not evidence of demand specifically for Seattle–Guadalajara flights. Separately, Guadalajara airport passenger traffic rose 5.0% in November 2024 compared with November 2023, according to airport operator Grupo Aeroportuario del Pacífico; that is an airport-wide, one-month comparison, not a measure of the Seattle route’s prospects.
Fares and flight time
Simple Flying reported that Alaska tickets were on sale with round-trip Saver fares listed at $615. Fares can vary by travel date and availability. For comparison, Volaris advertises fares from $155 and describes its Seattle–Guadalajara service as regular and frequent. The airline puts the average nonstop flight time at about five hours. Its advertised starting fare is not necessarily comparable to Alaska’s reported round-trip Saver price, and travelers should check current prices and schedules before booking.
Guadalajara is Alaska’s third route to the airport, Simple Flying reports, following the airline’s year-round service from Los Angeles and seasonal flights from San Jose. The Seattle launch would extend that existing network while adding a third nonstop carrier to the city pair; the published schedule and fares may change before service begins.
