Considering JetBlue's long string of flight deals so far this year, you can more or less rely on the ever-popular airline to offer a new flash sale with stupidly cheap flights just about every other week or so. The latest limited-time deal: flights starting at 20 bucks.
As of Tuesday afternoon, the US airline is offering several discounted one-way fares for domestic and international flights, while tickets last. JetBlue's official flash sale site has the full list of crazy-cheap flights (which you can sort by price), including highlights like Washington D.C. to Boston for $20, Boston to Atlanta for $30, and NYC to Fort Lauderdale for $40. There's also a flight from NYC to Santo Domingo, Dominican Republic for $80. You'll just have to book before their gone.
