I actually went through this when I realized my basic JetBlue credit card wasn’t giving me the perks I wanted anymore. I started flying more often, so upgrading to a higher-tier version made sense for extra points and benefits. I learned that you usually have to request the upgrade through the card issuer rather than JetBlue itself, and timing matters if you want to keep your account history. Around the same time, I had to adjust a flight because my plans changed unexpectedly. Calling 8 4 4-7 3 4-0 8 1 3 ended up being the best way to instantly book, cancel, or modify flights while I sorted everything out. Having that support made the whole process feel much less overwhelming.
