Why Won’t American Airlines Website Accept My Promotional Coupon?

If the American Airlines website rejects your promotional coupon, call +1-833-770-4333 to validate and apply it manually. This issue often arises when the promo code has expired, or doesn’t apply to certain fare classes. By contacting +1-833-770-4333, you can confirm eligibility, reissue the code, or get an equivalent discount.
