As with JetBlue's previous flash sales, though, this latest one comes with some fine print; namely, the discounted rates are only available for flights on specific travel dates. For example, if you want a $20 flight from NYC to New Orleans, you'll have to travel on December 13th. Other flights are even sooner than that, so be sure to check the exact dates before you get too excited.
Again, this is only the first of 12 deals JetBlue plans to unveil every day at 1pm ET for the holidays. All said, if this first deal is any indication of the rest, there's a chance you'll score a cheap vacation in no time.
