I wrote them recently because we are traveling May 3-16. Here is their response. (sorry it doesn't really help, but they are aware we are waiting)
Thank you for your email to JetBlue Airways regarding the date our extended JetBlue flight schedule
will be published. We appreciate the opportunity to answer your question.
We recognize that you are anxious to make your future travel plans, and regret any inconvenience the
wait may be causing.
Because we're busy adding new flights, new aircraft and new cities, we've been keeping our schedules
short term. We are trying to spare our customers the inconvenience of having the schedules change
after they have already purchased their tickets.
As our Marketing and Scheduling Departments work together to coordinate this growth, our schedule
date is extended and becomes available for purchase. We are not advised ahead of time a specific
release date for the new flight schedule. We encourage you to stay tuned to jetblue.com for the
announcement; when the dates you are looking for are released, you may book immediately online, or
call us at 1-800-JETBLUE (538-2583) and one of our Reservation Crewmembers will be happy to assist
you.
Thank you for taking the time to write to us. We hope to welcome you onboard a future JetBlue
flight.
Sincerely,
Customer Commitment Crew
