Amex Offers 20% Transfer Bonus to Aeromexico

American Express is offering a 20% bonus when transferring Membership Rewards points to Aeromexico, running until October 30, 2026. This promotion boosts the effective transfer ratio from 1:1.6 to 1:1.92.

The increased ratio does not affect Aeromexico's award chart or redemption values, so travelers should evaluate whether the airline's routes and pricing justify the transfer.

Redemption flexibility remains unchanged, and there are no caps on the bonus amount. However, it is essential to check Aeromexico's award prices before transferring points, as its award structure often delivers less value than partners like Delta or Air France.
