What Happens If American Airlines Delays Your Flight?
For a controllable American Airlines delay, however, the airline currently commits to meal assistance when the delay causes passengers to wait three hours or more. American also commits to rebooking for significant delays and hotel-related assistance for qualifying overnight disruptions.
Your best move at the three-hour mark is to check your American app and ask the airport agent what assistance has been issued. If you are already holding a meal voucher, using it may be simpler than paying out of pocket and later trying to recover the expense.
