JetBlue has announced its seasonal flash sale that allows you to pick various flights from cities across the country starting at just $20, plus fees one-way.

And with all things that seem too good to be true, there is a catch.  You only have just a few hours to book this flight deal.  The flash sale ends at 11:59 p.m. EST (sorry West Coast).

The flights are good for travel from September 1 through November 1, 2019, and are available from cities such as New York, Boston, Ft. Lauderdale, Long Beach, Tampa, and Washington D.C.

International trips to destinations like Bermuda and Grand Cayman can also be purchased at reduced prices.

Also keep in mind that if you purchase a ticket, they are classified under JetBlue’s Blue Class. This means you will not get a checked bag and you will have to pay extra if you change your mind unless you are an elite member with the carrier.

Here’s an example of what you can book:

From Boston

One-way trips to Martha’s Vineyard, Charleston, South Carolina, and New York City are starting at $20 one way.

International trips to Bermuda, San Juan, Puerto Rico, and Santiago are starting at $70 one-way.

From Fort Lauderdale

International trips to St. Maarten and the Grand Cayman are starting off at $70 one-way.

From New York City

New York City offers the most options domestically and internationally.

Flights to Boston are starting at $20 one-way and flights to New Orleans can be purchased for $40 one-way.

International destinations to Bermuda or San Juan can be purchased for $60 and $70 one-way.
