March 9, 2023

Southwest Airlines will add four new weekend-only routes as it extends its booking schedule into November.

The new fall schedule will see Southwest grow in Kansas City, Missouri, with two new international routes and in Long Beach, California, where the carrier will add service to the Pacific Northwest.

Southwest also will expand its schedule at Denver International Airport (DEN) — already the busiest airport in its network. It will not add any new destinations, but in October, Southwest’s schedule will increase to 310 departures each weekday – up by seven daily departures from its current schedule.

As for the new routes, Kansas City International Airport (MCI) is getting nonstop service to both Montego Bay, Jamaica, and Cabo San Lucas, Mexico. Service on both routes will be seasonal, beginning Oct. 7 and with one round-trip flight each Saturday.

Southwest notes that its new Kansas City routes come “on the heels of [the airport] opening its new state-of-the-art terminal last week.”

To the west, Southwest will add new destinations to its operation at Long Beach Airport (LGB). Service to Boise and Portland, Oregon, will begin Oct. 7, with flights on both routes operating on Saturdays and Sundays.

The route map changes come as Southwest extended its booking schedule through Nov. 4. While most big U.S. airlines publish schedules about 11 months in advance, Southwest’s booking schedule goes about seven months, with the carrier extending that window each month.
