About this route
Seattle to Anchorage flights
Seattle to Anchorage is Alaska Airlines' signature route, connecting the Lower 48 with Alaska's largest city. As the primary gateway to the Last Frontier, this route serves tourists heading to Denali and the Kenai Peninsula, oil and fishing industry workers, military personnel stationed at JBER, and Alaskans making supply runs to the lower states. Alaska Airlines dominates with extensive frequency.
Anchorage weather can be challenging — volcanic ash from Cook Inlet volcanoes, winter darkness, and strong crosswinds can affect operations. The flight path over the Pacific and British Columbia coastline means limited alternates. Landing alerts are particularly valuable on this route where weather-driven schedule changes are more common than in the contiguous states.
