Wow, JetBlue responds to emails incredibly fast.
Unfortunately, not the answer I was hoping for...
Hello Daniel,
We regret that you were not able to maintain your Mosaic status for 2017.
Because your status will expire after tomorrow, all future changes and cancellations would incur a
fee. To avoid paying a fee, we recommend that if you need to cancel your reservation, you do so
prior to losing you status.
Thank you for your loyalty. We hope to welcome you onboard again soon.
Kind regards,
Andrea
