Best wishes. The Jet Blue website is notoriously HORRIBLE, that would be really concerning to me, that the website will not recognize your confirmation code. I would be really mad, that you booked it a month ago, and then they cancel the whole connection out of FLL, a month later.

We booked our flights originally in October of last year. I am very happy that we re-booked on AA ASAP, as the FF miles for our trip have gone up from 20K each to over 30K, if one were to book it now, less than a week later.
