I've never flown JetBlue, and wondered about the history of their prices. Do they get higher as you get closer to the departure date? I have one DD flying down to WDW on Nov. 10th with her 5 DH and 5 kids. I have another DD flying down on Nov. 25th with her DH and 3 kids. I think they should book their flights now. I'm so used to SW where you can easily change your flights if a better price comes up. Please advise on jetBlue policies!
