United’s commitment:
When customers are denied boarding or downgraded involuntarily due to an overbooked flight or a change in aircraft, they will be compensated and treated fairly and consistently.

What this means for you:
Customers will be notified of check-in requirements that can help them avoid being "bumped" from a flight. Upon request, we will advise customers if a flight is overbooked and we will provide our policies and procedures for denied boarding. Customers who have been involuntarily denied boarding will be booked on the next available flight to their original destination and will be compensated accordingly.

Helpful suggestions:
Please arrive at the airport in plenty of time to check your bags. For domestic flights we suggest arriving 90 minutes prior to scheduled departure if you are checking bags and 60 minutes if you have carry-on items only. For international flights, we suggest arriving two hours prior to scheduled departure.

On occasion, security lines may be longer than usual. Customers can check Services & information for specific airport information prior to leaving for the airport.

To secure your seat, please be at your gate and ready to board the aircraft at least 20 minutes prior to scheduled departure.
