Overview
- On Oct. 22–23 JetBlue published detailed TrueBlue rules that grant unlimited complimentary, space-available BlueFirst upgrades to all Mosaic tiers and to JetBlue Premier Cardholders who pay with the card.
- Eligible travelers are automatically added to an upgrade waitlist at check-in and upgrades begin clearing 60 minutes before departure with positions visible in the JetBlue app.
- Upgrade priority follows Mosaic 4 through Mosaic 1 and then Premier cardholders, with tiebreakers that include paying with a JetBlue card, purchasing an EvenMore fare, and current-year tiles.
- Move to Mint certificates are rebranded as Premium Upgrade Certificates redeemable for Mint or BlueFirst, usable from booking until two hours before departure, require one to four certificates per one-segment upgrade, and can be earned through Perks You Pick at Mosaic 2–4.
- BlueFirst service begins Dec. 8, 2026 and most broader TrueBlue changes take effect Feb. 1, 2027, but small BlueFirst cabins, the late 60-minute clearing window, fare and companion limits, and JetBlue’s incentive to sell premium seats may restrict how often customers actually receive free upgrades.
