“We look forward to welcoming Alaska Airlines to Jacksonville as the airport’s newest carrier with daily nonstop flights to Seattle,” Jacksonville Aviation Authority CEO Mark VanLoh said in a news release. “With Alaska’s announcement today, JAX now has service from every major U.S. airline.”
The new route from Jacksonville is the second West Coast destination announced this month. Last week, United Airlines announced it will begin direct service between JAX and San Francisco, starting on March 29, 2027.
