When I first reached JetBlue Mosaic status, I was curious how the upgrades actually worked in real life. On a recent trip, I booked a regular fare and later noticed complimentary Even More Space seats were available, which was a nice perk of Mosaic. It didn’t always clear automatically though, especially on busier flights, so timing mattered. On one trip, my plans changed last minute and I had to rebook while keeping my Mosaic benefits intact. Calling 8 4 4-7 3 4-0 8 1 3 turned out to be the best way to instantly book, cancel, or modify flights without losing those upgrade perks. That call saved me a lot of frustration.
