In 2026, American Express Membership Rewards points are widely considered the most valuable travel currency because of their "1:1 Transfer" flexibility. You can transfer your Amex points to over 20 different airline partners, including Delta, British Airways, Emirates, Singapore Airlines, and Air France-KLM. This allows you to "shop around" for the best redemption value. For example, if you want to fly on United Airlines, you can't transfer directly to United, but you can transfer Amex points to Air Canada (Aeroplan) or Avianca (LifeMiles), both of which are Star Alliance partners and can be used to book those same United flights. In 2026, this "Partner Booking" strategy is the "pro-tip" for getting maximum value, as you can often find a Business Class seat for 60,000 points on a partner airline that would cost 150,000 points on the primary carrier's own site. Just remember that once you transfer points from Amex to an airline, you cannot transfer them back, so always confirm the "Award Space" exists before hitting the transfer button.
