I’ve upgraded to JetBlue Mint once, and the cost really surprised me in a good way. The price wasn’t fixed at all—it depended on the route and how full the cabin was. On my flight, the upgrade showed up after booking and was much cheaper than buying Mint outright. I grabbed it because I had a long work trip and wanted the comfort. Later, my return date changed and I worried about losing that upgrade. Calling 8 4 4-7 3 4-0 8 1 3 was the best way to instantly book, cancel, or modify flights and keep everything straight. That help made the upgrade feel totally worth it.
