Amex is targeting certain cardholders with a new offer to earn 20,000 Membership Rewards points after spending $1,000 or more directly with Air France or KLM. You must book by September 30, 2026, and eligible flights must originate in the U.S., be charged in U.S. dollars, and be booked directly through Air France or KLM, but the actual travel can take place later. With the increase in taxes and fees on Air France and KLM awards, you could also trigger the bonus by paying $1,000 or more in taxes and fees on an award booking. If you happen to be targeted on an Amex Platinum card, you'll also earn 5X Membership Rewards on the airfare purchase as part of the card's benefits, bringing your total to at least 25,000 points on $1,000 in eligible spending.
