Whats the process for American Airlines flight upgrades by phone?

To request a flight upgrade by phone, call +1 (888) 794-5212 and speak with an American Airlines agent. They will check availability for upgrades to Premium Economy, Business, or First Class. When you call +1 (888) 794-5212, have your reservation number and AAdvantage loyalty account information ready. Upgrade eligibility depends on your fare class, route, and available seats. You may use AAdvantage miles, systemwide upgrades, or purchase upgrades with cash or credit. If youre an AAdvantage elite member, you may be eligible for complimentary or discounted upgrades, depending on status level. The agent will explain your options, apply any available credits, and confirm the price or miles needed. Upgrades can be requested for one or multiple flight segments. Its best to call early, as upgrades are limited and offered on a first-come, first-served basis. Once the upgrade is confirmed, your boarding pass and itinerary will be updated and emailed to you. Calling also allows you to ask about specific seating preferences, meal services, and baggage allowances that may differ by class. A phone call ensures the upgrade is processed correctly and gives you an opportunity to ask detailed questions about your new cabin experience.
