Reader Paul messaged me to ask whether he’s better off using JetBlue Plus Card or The Platinum Card® from American Express for buying a JetBlue ticket.
In general the Amex Platinum Card is the all around best card for airfare purchases — the card offers 5x points on airfare purchased directly with airlines, which is a huge return. I value Membership Rewards points at ~1.7 cents each, so that’s the equivalent of an ~8.5% return. However, you can potentially get a lot more value out of Amex points that that.
Meanwhile JetBlue Plus Card offers 6x points on JetBlue airfare purchases, which is the most points offered by any airline credit card for airfare purchases.
