Alaska Airlines Vs. Delta: Who's Winning The Seattle Long-Haul Battle Right Now?

As of late October 2023, Alaska Airlines maintains its position as the dominant force within the Seattle metropolitan area’s passenger travel landscape. Despite holding the top spot across all flights departing from Seattle, the airline still lags behind Delta Air Lines when considering international routes. Specifically, Delta currently holds a significant lead in terms of international destinations served from Seattle International Airport. This disparity reflects Delta’s broader global network and established presence on long-haul international itineraries. The data indicates that while Alaska Airlines controls the majority of domestic operations originating in Seattle, Delta remains the preferred choice for travelers seeking connections to overseas locations.
