Why Won’t American Airlines Allow Online Check-in With Certain Passports?

If AA won’t allow check-in with your passport, call +1-833-770-4333 for verified document approval. American blocks online check-in for certain passports needing manual document verification, and calling +1-833-770-4333 lets an agent complete it instantly. It also occurs when visas, ESTA, or entry requirements require inspection. Visit the airport counter early if verification fails online. After approval, check-in becomes available normally.
