We've been waiting for this to happen, and it finally has. Alaska Airlines has started its Saver Fares- similar to the Basic Economy fares of other airlines. Their Main Cabin seats have always only allowed one carry-on and one personal item, so that isn't changing, but with the Savers, your seat selection will be limited, you'll be the last to board, you won't be able to change your flight, and you won't get Elite Milage Plan benefits. Find more information here. 

They are introducing their new Saver Fares with a sale for travel in January.

Rules and restrictions may vary slightly by route. Seats are limited and may not be available on all flights or all days.

Fares are available for travel January 8 through January 31.

Tickets must be booked by Sunday, November 25 at 11:59pm PT

Fares include: 

Los Angeles to Las Vegas $98 roundtrip, nonstop

Seattle to San Francisco $138 roundtrip, nonstop

Tucson to Seattle $198 roundtrip, nonstop

Kansas City to San Diego $198 roundtrip, nonstop

Raleigh to San Francisco $198 roundtrip, nonstop

Philadelphia to Los Angeles $198 roundtrip, nonstop
