I had to look into this when I helped a close friend who’s active duty book a JetBlue flight. JetBlue is pretty supportive of military travelers, but seat upgrades aren’t automatically guaranteed just for military status. From what I’ve seen, upgrades still depend on availability, fare type, and sometimes Mosaic status. My friend’s plans changed last minute, and we needed to adjust the booking while keeping the best seat option possible. 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 and get clear answers without confusion.
