JetBlue is having another two-day flash sale with cheap flights available this spring to many popular destinations across the U.S. — and a few in the Caribbean.

Cheap travel dates are available from March 13 to June 20, 2018, making this the sale for anyone who hasn't yet booked a trip for spring break. (If you're lucky enough to have one of those.)

The cheapest routes, at $44 one-way including taxes and fees, are between Long Beach and Reno, Longbeach and Oakland, New York City and D.C., and New York City and Portland, Maine. There are also $49 flights between Boston and Atlanta, Atlanta and Orlando, San Francisco and Long Beach, Nashville and Fort Lauderdale, and Fort Lauderdale and New Orleans.

Flights to Orlando — home of Mickey, Minnie, and Harry Potter World — start at $59 one-way from cities around the country.

There are also flights to Washington, D.C. starting at $54, just in time to book a trip to see the cherry blossoms.

To take advantage of the sale, travelers must book before midnight on Wednesday, and know that JetBlue's sale has blackout dates around Memorial Day. Fares include taxes and fees, but they are “Blue” fares, meaning checking a bag is not included. (Here's a breakdown of JetBlue's baggage fees.)
