How can I modify an existing booking with American Airlines?

First identify who issued and controls the ticket, then retrieve the exact American Airlines itinerary through the official manage-booking path. Compare the original and requested airports, dates and segments; check whether the change is voluntary or airline-initiated, whether travel has started, the fare rules, the operating airline and the live price difference before confirming anything. For American Airlines specifically: American uses a six-letter confirmation code or eligible ticket/account context to retrieve and modify a trip. Voluntary change options depend on timing and fare rules; a Basic Economy restriction and same-day change are distinct branches.
