I tried JetBlue’s bid upgrade program on a longer flight when I didn’t want to pay full price for Mint but still hoped for a better seat. After booking, I got an email inviting me to place a bid, and I chose an amount I was comfortable with. A day or two before departure, I found out my bid was accepted, which felt like a nice surprise. On that same trip, my return plans changed and I had to adjust everything quickly. 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 the upgrade. That experience made the bidding option feel low-risk and worth trying.
