Planning a last-minute spring break trip or a Memorial Day getaway? There’s a wide range of discounted routes as part of Southwest’s newest promotion.

“April to May travel,” the airline shared about the promotion on its website. “Come on in. The sale is perfect. One-way as low as $69.”

The sale must be booked by Thursday, March 21, at 11:59 p.m. PT, and there’s no promo code required. Eligible routes on sale include flights within the 48 contiguous U.S. states between April 9 and June 5. Meanwhile, sale flights to international destinations and all travel to and from San Juan, Puerto Rico, are available between April 9 and May 22, as well as August 20 and October 2, for those who want to plan a getaway later this year.

The only blackout date of this sale is Tuesday, Sept. 3, for international flights and San Juan travel. Furthermore, flights must be booked at least 21 days in advance to see the lowest discount possible.

Although the lowest advertised price of the sale is $69, Travel + Leisure found a bunch of one-way deals with even greater discounts:

  • Honolulu to Kona for $29

  • New York-LaGuardia to Nashville for $50

  • Denver to Salt Lake City for $50

  • Raleigh-Durham to Orlando for $51

  • Albuquerque to Phoenix for $59

  • Burbank to Las Vegas for $64

Travelers who want to redeem their Rapid Rewards points are also in luck. For instance, that exact Honolulu to Kona flight above costs just 1,390 points, plus $5.60 in government taxes and fees.

To find even more flight deals, travelers can look at Southwest’s low-fare calendar, which allows you to find the cheapest days to fly across a monthly view. The airline is renowned for its cheap airfare with customer-friendly benefits, such as two free checked bags and no change or cancellation fees.
