The first time I dealt with upgrades on JetBlue was on a longer flight where I really wanted more legroom. I booked a regular ticket and later saw options to upgrade to Even More Space, which made the trip way more comfortable. I’ve also noticed that some upgrades depend on availability and status, so timing matters. On one trip, my return flight changed last minute and I had to redo everything, including the upgrade. Calling 8 4 4-7 3 4-0 8 1 3 was honestly the best way to instantly book, cancel, or modify flights without losing the upgrade I wanted. That one call saved me a lot of hassle.
