If you’re itching to travel but not up for paying full price for a flight out of town, you might want to jump on this flash sale from JetBlue. The airline is celebrating its 20th anniversary in a very big way.

Through midnight Eastern Time on 2/12/2020 you can book a flight for as low as $20. Obviously, where you’re traveling and how popular that route is will affect the price of the flight. Some flights are currently closer to $100, but still. That’s a great deal.

What’s the catch? Well, obviously you need to act fast. The sale ends soon and once flights are sold out, there won’t be any seats left to book. Also, you need to be willing to travel on a Tuesday or Wednesday.

The flight sale is valid for flights departing February 19th all the way through June 17th, but there are a few black out dates. You won’t be able to travel from March 18 through the 31 or April 14th through the 21st.

This isn’t the first time that JetBlue has offered an incredible discount on their flights. For their 10th anniversary, the airline celebrated by offering flights for as low as $10. 

JetBlue’s website makes it easy to choose your local airport and see what locations are eligible for this 20th anniversary discount. The fares that are on sale are the Blue Basic fares. With Blue Basic there is an additional fee for checked bags and advanced seat selection. Also, it’s not possible to change or cancel these flights. If you upgrade to Blue, the fare costs more but includes advanced seat selection, and you can change your flights for an additional fee.
