If you notice a misspelled name on your American Airlines ticket, you can typically correct it by contacting customer service. Minor spelling errors (such as a single letter mistake in the first or last name) are often allowed to be corrected without penalty. To request a change, call American Airlines at their customer service number or use their online support tools. You may be asked to provide identification and flight details. It’s best to make corrections as soon as possible, as the airline may require several days to process the request before your flight. Major name changes generally aren’t allowed.
