Southwest Airlines is celebrating its 53rd anniversary with $53 airfares.
Travelers looking to score a deal should book at 11:59 PM PT on Thursday.
The $53 one-way tickets are only available on select days and routes, but include flights to Hawaii, Puerto Rico and international destinations, according to Southwest.
Eligible travel must occur Monday-Thursday or Saturday between August 6 and December 18 for flights within the lower 48 with September 2, October 14, November 22-27 and November 29 through December 2 as blackout dates.
Flights to Hawaii, Puerto Rico and international destinations must operate on Tuesdays or Wednesdays between August 20 and November 20, with a blackout scheduled for September 3.
Some of the routes currently advertising fares as low as $53 are Atlanta to Tampa and Los Angeles to Phoenix.
Full availability and terms and conditions are listed on Southwest’s website.
Will there be changes in Southwest?
Southwest Airlines has long been known for its open seating policy, all-economy cabins and multiple free checked bags on every ticket. But amid scrutiny from activist investors and changing customer preferences, the airline’s CEO has indicated the business model could soon change.
