Your name on your plane ticket and your passport or other official government documents must match, according to airline policy. Furthermore, you might not be allowed to board your plane if they don't match. According to American Airlines name change policy, you must thus start the name correction or amendment process on your ticket. Visit the official airline website or give the customer support number a call for further details. Should they be unavailable, assistance can be obtained by calling the consolidation desk at +1-800-633-0441.
