JetBlue's program is adequate for the real frequent flyer, not the occasional. If the internet bonus continues, 5 trips a year equals a free trip. That's about how much Silver elites (different names for different airlines) travel.

The 12 month window is somewhat tight, but useable if it's not too hard to get a seat or if you can change the date of travel later.

The WSJ reports that JetBlue would like it if all airlines ended their programs. They also said that it may be hard to get seats because of high load factors. Southwest gets around this passenger unfriendly situation by allowing any seat to be an award seat.
