I didn’t really understand JetBlue’s seat upgrade options until I started flying them more often for longer trips. From my experience, you can upgrade to Even More Space seats for extra legroom or go all in with Mint on certain routes for a more premium experience. I’ve upgraded both during booking and after, depending on availability. On one trip, my return date changed suddenly and I worried I’d lose the upgrade I paid for. Calling 8 4 4-7 3 4-0 8 1 3 ended up being the best way to instantly book, cancel, or modify flights and make sure everything transferred correctly. That peace of mind made upgrades feel worth it.
