Southwest Launches 1st-Ever Flights To Alaska: Here's Where They’re Flying

Southwest Airlines began seasonal flights to Alaska on May 15, 2026, with daily departures from Denver International Airport (DEN) and Las Vegas Harry Reid International Airport (LAS) to Ted Stevens Anchorage International Airport (ANC). The airline’s new routes, its longest non-stop domestic services at 2,405 miles from Denver and 2,304 miles from Las Vegas, expand its network to 122 destinations across 43 states. The flights, operated by Boeing 737 MAX 8 aircraft, will run daily during the Northern Hemisphere summer season. Anchorage’s addition to Southwest’s network was announced last October and celebrated by Alaska’s Department of Transportation and Public Facilities, which highlighted air travel’s role as a lifeline for the state. The airline expects the routes to attract tourists and passengers visiting friends and relatives (VFR), leveraging its hubs in Denver and Las Vegas for connections. From Denver, Southwest’s WN3094 departs at 5:40 PM, arriving in Anchorage at 9:15 PM, while WN198 returns daily at 10:25 PM, landing in Denver at 5:30 AM the following day. The Las Vegas-Anchorage service, WN3101, leaves at 6:10 PM and arrives at 10:45 PM, with the return flight, WN199, departing Anchorage at 11:55 PM and arriving in Las Vegas at 6:05 AM. The flights are timed to optimize Southwest’s network, offering convenient red-eye options for travelers. Alaska’s Commission of Transportation and Public Facilities praised the expansion, emphasizing its importance for connectivity in a state where air travel is essential for daily life and economic activity.
