American Express announced today that the Business Platinum card will no longer include First and Business Class tickets booked on an airline that is not your selected airline. The change will go into effect on September 18, 2025.
Previously economy flights needed to be your selected airline in order to get the 35% rebate while First and Business Class tickets earned the 35% rebate on all airlines.
Ouch. Many report, unofficially, being able to change their selected airline multiple times in mid-year to a domestic airline, but not an international airline, so that can help somewhat.
