Southwest Airlines is expanding its network to Alaska for the first time, launching new seasonal flights to Anchorage from Las Vegas and Denver beginning in May 2026. The new routes will give travelers direct access to Alaska’s breathtaking scenery — from glaciers and mountains to the Northern Lights — just in time for summer adventure season. This move marks a major milestone for Southwest as it enters one of America’s most remote and scenic destinations, offering travelers a new way to explore the “Last Frontier” with the airline’s signature low-cost service.
