How to Book American With Amex Points

Which program to transfer into

AAdvantage miles book American's own flights. The banks that list AAdvantage are Citi ThankYou Points (1:1 on premium cards, 1:0.7 on other cards). Amex is not in that sentence. The partner route an Amex balance can fund is book American with Avios.

The ratio is read from the transfer list. Amex also lists Iberia Club and Aer Lingus AerClub. Those are separate rows. This guide books American through British Airways, which is the partner page we publish. It does not tell you to move Amex points to Iberia or Aer Lingus for an American flight.

Amex's list has no Atmos Rewards row. Book American with Atmos Rewards names its bank: Bilt Rewards.

This directory row for British Airways Avios does not set a block size, a minimum, or an official transfer time on the Amex side. Read those figures on the Membership Rewards transfer screen. There is no Amex to British Airways transfer guide on this site.

Amex's Flying Blue terms say Amex charges an excise tax offset fee only for points transferred to a U.S. airline frequent flyer program. British Airways is not a U.S. airline program. Confirm the fee line on the Avios transfer anyway. This row does not carry its own no-fee statement.

How to transfer Amex points and book

British Airways says you can use Avios on American Airlines. A search shows British Airways seats first, then partner seats. For help booking one partner, BA says to call. A partner Avios price can differ from a British Airways price and depends on the route, the distance, the date and the cabin. Cancel at least 24 hours before the first flight if you want a refund.

1. Find the American Airlines flight and note the flight number and the date.
2. Search that flight with British Airways before you transfer. Move only the points the seat on that screen requires.
3. If the American flight shows, transfer Amex points to British Airways Avios at 1:1.
4. Book, then check that the confirmation shows the American Airlines flight number.

On American Airlines, Iberia and other oneworld partners, British Airways says the cash for taxes, fees and carrier charges varies. It is not the flat cash amount BA uses on its own flights.

For a departure in the United States, British Airways charges nothing to book a reward flight on ba.com. A date, time or cabin change is $55, and a cancellation that redeposits Avios is $55. Each fee is per person and per ticket. Booking by phone is $25. Gold members do not pay the extra service centre fee. A Gold Priority Reward booking has no change charge. Canada uses different amounts on the same page.

The click path inside Membership Rewards is on the transfer screen. This page does not copy menu labels that are not in the transfer data. Citi holders who want AAdvantage miles use how to transfer Citi points to American. That guide does not spend Amex points.

Chase holders have the same Avios idea with a different bank: how to book American with Chase points. The Chase ratio is 1:1, checked October 16, 2026. Do not mix the two balances in one transfer.

When Avios is the better route

For an Amex balance, Avios is the published route onto American. AAdvantage is the better program when you already hold the miles, or when you are moving Citi ThankYou Points (1:1 on premium cards, 1:0.7 on other cards). Those banks are not Amex.

We value an Amex point at 2.0 cents per point, an Avios at 1.35 cents per point, and an AAdvantage mile at 1.45 cents per point (The Points Guy, November 2026).

Avios are listed below an Amex point, so the award has to beat 2.0¢ per point after the cash British Airways adds.

Search the American-operated flight on British Airways. If you also hold AAdvantage miles from another bank, search there too and keep the cheaper result. A Chase balance is a separate transfer at its own ratio, on its own page. Atmos is not an Amex option.

Run your own balance through the points value calculator.

Business class is a strong redemption when the points price and the cash on top still beat paying cash. Leave the points in Membership Rewards when British Airways does not show the American flight.

Learn this properly

Lesson 11: Transfer Partners & When to Use Them explains why Amex points can book another airline's seats. Points values prices Amex points against Avios. AAdvantage miles you already hold are a different balance from the Avios this transfer creates.
