To transfer American Express Membership Rewards points to travel partners, you must first log into your account at americanexpress.com and navigate to the "Rewards & Benefits" section. From there, select "Earn and Redeem" and then click "Transfer Points." You will see a list of over 20 airline and hotel partners, such as Delta SkyMiles, British Airways Executive Club, and Hilton Honors. If it is your first time transferring to a specific partner, you will need to link your loyalty program account number to your Amex profile. Most transfers occur at a 1:1 ratio, though some partners have different rates (e.g., Hilton is often 1:2). Once linked, enter the amount of points you wish to move and confirm the transfer. Note that transfers are irreversible—once the points leave Amex, they cannot be moved back. Additionally, for transfers to U.S.-based airlines (like Delta or JetBlue), Amex charges an excise tax offset fee of $0.0006 per point, capped at $99 per transaction.
