In celebration of Valentine's Day, the airline is offering a whole bunch of domestic and international one-way fares, with some truly exceptional steals to be had. JetBlue's official flash sale site has all the deals, and you can easily sort them by price, departure city, and destination. You just have to book before 11:59pm ET on Wednesday.
Highlights include Chicago to Ft. Lauderdale (and vice versa) for $39, Boston to Atlanta for $49, Pittsburgh to Ft. Lauderdale for $59, and Baltimore to Orlando for $59. And if you're looking to get your passport stamped someplace where it definitely isn't snowing, there are also super-affordable flights to places like Mexico City, Havana, St. Maarten, Nassau, and Cartagena, Colombia.
