I completely forgot to mention the best part of JetBlue’s sale: The airline has $69 one way fares from JFK to Puerto Rico and to the Dominican Republic. This is the lowest fare I’ve ever seen to these markets. The $69 fare from San Juan, though, appears to be available primarily on the 3:15 am flight (it arrives at 6:10 or so). I believe that is the worst arrival/departure time combination of any domestic flight. If you know of any flight that’s equally has miserable as one that leaves at 3:15 am, only to arrive at 6:10, please let me know.
