The company launched its 72-hour sale Tuesday morning, which means you only have until Thursday, June 6 to book a ticket.

A one-way fare starts at $49. They go up to around $79, $99 or $129 for longer flights.

The dates vary for travel to and from San Juan, Puerto Rico and to international travel destinations.

Hawaii is also in the mix, with tickets for interisland travel valid between September 3 - November 2, 2019.

Earlier this year, Southwest launched its sale of flights to Hawaii shortly after completing a test flight, which appeared to spark some fare wars in the friendly skies with other airlines.
