United Airlines customer service phone numbers

United Airlines operates separate phone lines for different types of calls. The main reservations and customer service line is 1-800-864-8331. This number handles new bookings, changes to existing reservations, and general questions about flights and fares.

If you have a frequent flyer account or are calling about MileagePlus rewards, use 1-800-241-6522. For baggage questions, lost luggage, or damage claims, call 1-877-435-9422. If you are calling from outside the United States, United has country-specific numbers listed on their website under "Contact Us".

Wait times vary by time of day and season. Early morning calls (before 8 a.m. Eastern) and weekday calls typically have shorter waits than evening or weekend calls. Holiday travel periods see significantly longer hold times across all lines.

What information to have ready before you call

Gathering details before you dial saves time on hold and speeds up your call. Have your confirmation number ready if you are calling about an existing reservation — it appears on your booking email and starts with letters like UA or UT. If you do not have the confirmation number, your last name and phone number will work instead.

For baggage claims or lost luggage, have your baggage tag number or the flight number and date of travel. For MileagePlus account questions, have your membership number or the email address associated with your account. If you are calling about a refund or credit, have your original booking reference and payment method information available.

Using the callback feature instead of holding

United's website offers a callback option that lets you request a call from an agent rather than waiting on hold. Go to united.com, select "Contact Us," and choose the callback option for your issue type. You enter your phone number and the system tells you the estimated wait time. An agent calls you back within that window instead of you sitting on hold.

This feature is available for reservations, customer service, and baggage questions. The callback window is usually accurate within 15 minutes, though it can shift during very busy travel periods. You do not need to stay on the website once you request the callback — you can close your browser and wait for the call.

Chat and email options for non-urgent questions

If your question is not time-sensitive, United offers chat support through their website and email support through their contact form. Chat is available during business hours and typically has a shorter wait than phone lines. Email responses usually arrive within 24 hours on weekdays, though it can take longer during peak travel seasons.

Chat and email work well for questions about policies, general information about flights, or issues that do not require when ready resolution. Phone is faster for urgent problems like missed connections, flight cancellations, or booking changes you need to make right away.

International calling and airport phone locations

If you are calling from outside the United States, United has dedicated numbers for major countries and regions. Visit united.com and search for "international phone numbers" to find the line for your location. International calls may incur long-distance charges depending on your phone plan.

If you are at a United airport terminal, customer service desks are located in the main terminal areas and can handle most issues in person. Airport agents can rebook flights, handle baggage problems, and answer questions about your reservation without a phone call. Wait times at airport desks vary by time of day and how busy the airport is.

What to expect when you call

When you reach a United agent, they will ask for your confirmation number or name and phone number to pull up your reservation. Have this information ready to move through the call faster. The agent will then ask what you need help with and either handle it directly or transfer you to a specialist if needed.

Most calls are recorded for quality and training purposes. If you are calling about a complaint or dispute, mention that early so the agent can flag the call appropriately. Agents can make changes to reservations, issue refunds or credits within policy, rebook you on different flights, and answer questions about baggage, seating, and special services.

Common reasons to call and what to expect

Booking changes like date, time, or passenger name corrections can usually be handled in one call. Baggage questions about weight limits, fees, or lost luggage require your baggage tag number or flight details. Refund requests go through a process that can take several weeks depending on the reason and your original payment method.

If your flight is cancelled or significantly delayed, agents can rebook you on the next available United flight at no extra charge, or on another airline if United cannot get you there sooner. For special services like wheelchair information, unaccompanied minor travel, or pet travel, agents can add these to your reservation or answer questions about policies and fees.

Frequently Asked Questions
