Interested in a last-minute, end of summer, or Labor Day weekend getaway? JetBlue has just announced a new flash sale, with tickets selling for as little as $20 to 20 destinations.

To take advantage, however, you’ll need to be free on a very specific date. There is a $40 flight from New York City to Orlando, for example — but it’s only available on a September 3 flight from Newark Liberty International Airport at 9:14 in the evening.

Those $20 tickets are valid on flights from Long Beach, California to San Jose and from Las Vegas to Long Beach (departing on August 13 and August 30, respectively).

There are also a number of $60 and $70 one-way flights to Puerto Rico, which depart from Boston, Orlando, Newark, Hartford, and Tampa between August 21 and September 3.

New York-based travelers have the most options, with flights to a handful of cities in Florida as well as New Orleans; San Juan, Puerto Rico; and Santiago, in the Dominican Republic.

The sale ends when tickets sell out, which could happen in less than an hour. If you don’t see any trips that work for you, be sure to follow @JetBlueCheeps and watch out for the #JetBlueFlashFares hashtag.
