Mosaic status qualification
We recognize you are probably not flying as frequently as you have in the past—and may have questions about your qualification for Mosaic. While our immediate priority is safely operating through the recovery, we did want to provide some reassurance as to your status qualifications.
If you qualified for Mosaic in 2020 from flight spend and qualifying points, you can trust we will offer new paths for you to qualify in 2021. For those with the JetBlue Plus Card, you can continue to earn Mosaic status with your annual spend.
As the coronavirus situation continues to evolve, we will be sharing our final plan for qualification in the coming weeks.
