How JetBlue seats & upgrades generally work
The essentials. Availability and price depend on fare, route, aircraft and timing.
Most fares let you choose a seat; Blue Basic assigns your seat later in the process and doesn't include advance selection at no cost.
If you're travelling as a family or group, book and select seats as early as you can — the best adjacent seats go first, especially on full flights.
JetBlue's Even More Space seats add extra legroom and early boarding for a premium on most fares. They're limited and sell out on popular flights.
Mint is JetBlue's premium lie-flat cabin on transcontinental and select international routes. You can book into it, and paid upgrades may be offered where space allows — availability varies a lot by route.
TrueBlue Mosaic members get better seat access and perks. Add your TrueBlue number so any benefit applies.
Seat and upgrade prices vary by route, cabin and timing and change constantly, so we don't list amounts. Tell us your flight and we'll check what's open and reserve it for you.
Seat options by fare
General guidance — what's included and what's paid depends on your fare and route.
Ways to move up
More than one path to more room or Mint — availability varies by route and day.
Pay to upgrade
Most predictable
- Book Even More Space at booking or later
- Book directly into Mint on eligible routes
- Paid Mint upgrade offers where space is open
- Price and space vary by route and demand
Mosaic perks
For status members
- Better seat access and boarding for Mosaic members
- Add your TrueBlue number so it's linked
- Perks apply on eligible fares and routes
- Not a guaranteed cabin upgrade — depends on availability
Add your TrueBlue number before you fly. Mosaic seat and boarding perks only apply if your number is on the reservation — easy to forget, easy to add.
