If American Airlines (AA) cancels your flight due to weather in 2026, they are generally not required to provide cash compensation or pay for hotel accommodations, as weather is classified as an "uncontrollable event." However, the airline will automatically attempt to rebook you on the next available flight to your destination. You can check your new itinerary via the AA app or at an airport kiosk. If the provided alternative does not work for you, you are entitled to a full refund to your original form of payment, even if you have a "non-refundable" ticket, provided you choose not to travel. In cases of major storms, AA often issues "Travel Alerts" which allow you to change your flight dates without a change fee or fare difference within a specific window. While they won't pay for your hotel, they may offer "distressed passenger" vouchers that provide discounted rates at local partner hotels, but these are given at the gate agent's discretion and are not a guaranteed right.
