American Express will add a new cap on spending for the American Express Platinum card of $500,000 per calendar year on flights purchased directly from airlines or American Express Travel. Normally these purchases earn 5x points and you’ll continue to earn 5x points on the first $500,000 in spend per calendar year, before it reverts back to 1x earning. Can’t imagine this affects many cardholders, but American Express is obviously bringing it in for a reason.
