The company began selling the $599 pass last week. It allowed for unlimited travel to the carrier's 56 U.S. and international destinations from Sept. 8 through Oct. 8. All open seats were included with no blackout dates, though tickets were based on availability and had to be booked at least three days in advance.

"We wanted to ensure those who bought the pass could get the flights they want, so we capped the number of passes we would sell," JetBlue spokeswoman Jenny Dervin told Reuters. "And we reached that number yesterday."

The offer had been due to expire Friday.
