A brilliant marketing idea (even if they don’t profit from it): JetBlue is offering a 1-time, $599 pass good for as much travel as you can squeeze in from September 8 – October 8 (one flight per day, please) across their entire network. International fees (which can add up) are not included. You have to actually book the flight 3 days in advance, and if you don’t show up they’ll ding you for $100.
The best part? If you already have a flight booked during that time, you can pay the difference between $599 and the fare and get the pass and fly all you want for the month.
(A quick additional note: Eastern Airlines sold a similar pass to similar destinations back in 1980 — 21 days unlimited travel for about $400 tax included. More detail here:
Just goes to show what a steal this is…)
