American Airlines, CSA Weekend 1 Practice Exam

During check-in, you must prove who you are and that you’re the person tied to the reservation. The combination of documents used together makes this verification reliable: a government-issued photo ID shows your identity; the reservation name confirms the booking is in your name; and a booking reference or ticket number lets the agent locate the exact reservation in the system. Relying on only one piece leaves gaps: an ID alone might not reveal which booking it belongs to; a reservation name alone doesn’t prove identity; a booking reference alone doesn’t verify who is traveling. Using all three streamlines the process and helps prevent misbooking or fraud, which is why this trio is typically required at check-in.
