Summer can be one of the most expensive times to travel in the US, especially around Memorial Day, Fourth of July, and Labor Day holidays. It’s common for airlines to hike up their prices by as much as $400 during the summer months, and oftentimes you have no choice but to pay. Luckily, Southwest has an alternative. Their “Summer of $69” sale includes peak summer travel to and from dozens of major U.S. airports. Despite its name, you can actually find flights for even cheaper than $69 — as low as $55, actually.

This deal only applies to flights on Tuesdays, Wednesdays, and Saturdays, from mid-June through November 3, 2018. While there are a few blackout dates around Labor Day weekend, they only affect flights to/from Florida and Nevada.

Some of the best routes include Nashville to Atlanta for $130 round trip, Austin to New Orleans for $166, El Paso to Los Angeles for $180, Tampa to Memphis for $196 and Seattle to San Diego for $212

Chances are if you’ve waited this long to book summer travel, you’re a procrastinator, so don’t make the same mistake and let this deal slide. To secure your last minute summer vacay, book tickets directly through Southwest by 11:59 pm on May 31.
