Yes, American Express charges a fee when you transfer Membership Rewards® points to U.S. domestic airlines (such as Delta, JetBlue, or Hawaiian Airlines). This fee is strictly to offset the federal excise tax that Amex must pay on these transfers. The current rate is $0.0006 per point, capped at a maximum of $99. For a transfer of 50,000 points, the fee would be approximately $30. You can choose to pay this fee with cash or by using a small portion of your points. Importantly, this fee does not apply to transfers to international airline partners like British Airways, Emirates, or Singapore Airlines, even if you are using them to book domestic flights via partners. In 2026, Amex also adjusted several transfer ratios for specific partners, so it is vital to check the latest conversion rates in the Membership Rewards portal before committing to a transfer.
