Best Way to Reach United Airlines by Issue

Reservations, Booking, and Flight Changes

For new reservations, booking help, flight changes, same-day changes, schedule changes, seats, upgrades, and trip questions, use United.com, the United app, chat, text support, or call 1-800-864-8331. If your issue is urgent because your flight is today, use the app, Agent on Demand, airport staff, or phone support.

Delayed, Canceled, or Missed Flights

If your flight is delayed or canceled, check the United app first for rebooking options, travel credits, meal or hotel information, and flight status. If you need help during a disruption, use Agent on Demand, airport staff, text UNITED to 32050, or call 1-800-864-8331. Keep boarding passes, receipts, delay notices, hotel receipts, meal receipts, and screenshots of rebooking options.

Baggage Problems

For delayed, lost, damaged, or missing baggage, report the issue as soon as possible at the airport or through United’s bag help tools. Call the Baggage Recovery Center at 1-800-335-2247 or text BAGS to 32050. Save your bag tag number, file reference number, receipts, delivery details, and photos of any damage.

Refunds and Travel Credits

For refunds, use United’s online refund request form. Refund eligibility may depend on the fare type, cancellation reason, schedule change, travel waiver, duplicate purchase, baggage issue, or other policy. If a refund is approved, check whether it was returned to the original form of payment or issued as a travel credit.

Customer Care Complaints After Travel

For complaints after a completed trip, use United’s Customer Care form rather than regular reservations. Include your confirmation number, ticket number, MileagePlus number, flight number, date of travel, route, receipts, photos, and a clear explanation of the resolution you are requesting.

MileagePlus Accounts

For MileagePlus account access, missing miles, award travel, account profile issues, Premier status questions, or MileagePlus service issues, call the MileagePlus Service Center at 1-800-421-4655. You may also be able to resolve many MileagePlus issues after signing in to your account.

Accessibility and Special Assistance

For wheelchair assistance, seating accommodations, service animals, medical devices, oxygen-related questions, mobility devices, accessible travel concerns, or disability-related travel support, contact United’s Accessibility Desk at 1-800-228-2744. If a disability-related issue occurs at the airport, ask for United’s Complaint Resolution Official.

International Travel Support

For international reservations, country-specific phone numbers, overseas support, passport or travel-document questions, and international rebooking issues, use United’s international reservations contact page or call United reservations. If you are already at the airport, speak with a United airport representative.

United Airlines Refund and Reimbursement Tips

Use United’s refund request form for refund requests instead of only calling reservations.

Save your confirmation number, ticket number, receipt, and cancellation notice.
For delayed or lost bags, keep the baggage file reference number and receipts for reasonable interim expenses.
For canceled or significantly delayed flights, save screenshots of rebooking options and any United notifications.

Check whether United issued a refund, future flight credit, travel certificate, or miles.
If you booked through a third party, the travel agency or credit card portal may need to process certain changes or refunds.
If United denies a refund and you believe you are entitled to one, submit a written Customer Care request and keep the case number.

United Airlines Baggage Complaint Tips

Report delayed, lost, or damaged bags as soon as possible at the airport or through United’s baggage tools.
Keep your bag tag receipt and 13-character file reference number.
Photograph damaged luggage before repairs or replacement.
Save receipts for essential purchases made while a bag is delayed.

Check claim deadlines carefully, especially for delayed, damaged, or missing contents claims.
Use United’s baggage tracing tool to check claim status.

United Airlines Scam and Account Safety Tips

Use United.com, the United app, or official United phone numbers when changing travel plans.
Be cautious of fake airline support numbers found in search ads, social posts, or unofficial websites.

Do not share your MileagePlus password, one-time code, passport number, or payment details with someone who contacts you unexpectedly.
If a caller says your ticket will be canceled unless you pay immediately by gift card, wire transfer, cryptocurrency, or payment app, hang up and contact United directly.
When using text support, verify that you started the conversation by texting UNITED or BAGS to United’s published short code.

Watch for fake refund emails after cancellations or widespread flight disruptions.

How to Escalate a United Airlines Complaint

Start with the support path that matches the issue: reservations, baggage, MileagePlus, accessibility, or refunds.
If the issue happened during travel, use the United app, airport staff, Agent on Demand, text support, or 1-800-864-8331.

For baggage issues, file a baggage report and keep your file reference number.
For refunds, submit the online refund form and save the confirmation.
For post-travel complaints, use United’s Customer Care form and include all flight, ticket, receipt, and case details.

For disability-related issues, ask for United’s Complaint Resolution Official at the airport or contact the Accessibility Desk at 1-800-228-2744.
If United does not resolve the issue, consider filing a complaint with the U.S. Department of Transportation Office of Aviation Consumer Protection.
