Looks like the intel was spot on. This just came out from the CP:
The JetBlue Talent Acquisition and Flight Operations Leadership Teams are pleased to announce that the new hire First Officer application window will be opening this Thursday evening, July 31 and will be open for at least 7-10 days. Candidates who apply during this window and are successful will be scheduled for interviews later this fall with class dates in early 2015. Interviews are granted on the basis of competitive evaluation. Candidates offered interviews will tend to have experience well above the published minimums.
If you have candidates you would like to refer, please write a letter of reference for them in advance, and provide it to them so they can upload to their application when they apply, as we do consider referrals in the selection process.
We are in the process of notifying all candidates that applied to the First Officer posting on November 22, 2013 that we are closing that posting and if they are still interested in a position at JetBlue, they should reapply when the window reopens this week. While there are still thousands of candidates in the former application, we wanted to open the window again to allow additional candidates to apply, and to refresh the candidate pool. Candidates who have interviewed over the past year and have received email confirmation that they have successfully passed phase II do not need to reapply. These candidates are in the pool awaiting class.
Only those who apply during this open application window will be considered for the First Officer position regardless of prior applications
