JetBlue has launched several flash sales like this in recent weeks, always with the same stipulations and fine print. Availability at these prices is extremely limited, and is only valid on specific flights and dates. Travelers can expect seats at these fares to sell out in a hurry too.
The other hangup for travelers is that these fares are only good in one direction. In other words, you’re on the hook for the return flight, assuming you need one — and odds are that portion of your airfare will be considerably more expensive than the flash sale price.
All that said, if any of the flights work with your schedule, there are some outstanding deals to be had. Act quickly!
