Passengers filing a complaint should gather the confirmation number, ticket number, flight number, travel dates, receipts, boarding passes, baggage records, screenshots, and previous Customer Service case information.
For a problem that is still occurring before or during travel, call 1-800-864-8331 or speak with United staff at the airport. Explain the problem clearly and provide your flight and confirmation information. If the issue involves rebooking, cancellations, seats, check-in, or irregular operations, resolving the matter while travel is still active can often provide more options.
For a completed trip or unresolved service issue, use United’s official Customer Care form at https://www.united.com/en/us/customer-care. Include the relevant flight details, ticket number, dates, employee information if known, and a concise account of what happened. Attach supporting documentation where the form permits it and save the case reference.
Refund, baggage, and loyalty disputes may need review by specialized United teams. MileagePlus complaints can use 1-800-421-4655, while ticket and travel issues can continue through Reservations and Customer Care. Keep receipts, baggage tags, mileage statements, and previous case numbers so United can review the complete history.
For a serious unresolved corporate matter, written correspondence can be sent to United Airlines Holdings, Inc., 233 South Wacker Drive, Chicago, IL 60606. Include your full contact information, flight details, ticket number, complaint case numbers, prior responses, and the resolution requested. Attach copies rather than original documents and retain proof of delivery.
If the airline complaint remains unresolved, U.S. passenger-service complaints can be submitted to the U.S. Department of Transportation Aviation Consumer Protection process. Other disputes may involve the card issuer, travel insurer, baggage insurer, or applicable consumer authority depending on the issue. Keep United’s written responses, receipts, flight records, and case numbers before escalating.
