United Airlines customer service phone numbers by reason

United Airlines operates different phone lines depending on what you need. The main reservations and general customer service number is 1-800-864-8331. This line handles new bookings, changes to existing reservations, and general questions about your account or upcoming flights.

If you have a specific issue — a lost bag, a flight delay, a refund request, or a seating problem — you will reach a faster resolution by calling the line that handles that category. United routes calls differently based on your reason, so having the right number saves you from being transferred multiple times.

Wait times vary by time of day and season. Early morning (before 7 a.m. ET) and late evening (after 9 p.m. ET) typically have shorter queues. Calling on weekdays rather than weekends also reduces hold times, though no time is may provide to be quick during peak travel periods.

Key Takeaways

  • The main United Airlines number is 1-800-864-8331 for reservations and general questions, but specialized lines exist for baggage, refunds, and flight changes.
  • United routes calls to different departments based on your issue, so calling the correct line the first time reduces your total wait time.
  • Early morning and late evening calls typically have shorter hold times than midday or weekend calls.
  • You will need your confirmation number or ticket number ready when you call, regardless of which line you reach.

Numbers for specific issues

For baggage and lost luggage, call 1-877-926-8532. This line connects you directly to United's baggage department, which can file a claim, track a delayed bag, or help with damage to your luggage. Have your flight number, travel date, and baggage tag number ready.

For refunds and cancellations, call the main number 1-800-864-8331 and ask to be routed to the refunds department. If you cancelled a flight and want a refund rather than a credit, or if you believe you are owed money for a cancelled or significantly delayed flight, this department handles those requests. Processing times vary, but you should expect a decision within 30 days.

For flight changes and rebooking after a cancellation or missed connection, the main reservations line 1-800-864-8331 can rebook you on the next available flight. If you are stranded due to a United cancellation or delay, ask specifically for the customer relations team, which has more flexibility to rebook you on competing airlines if needed.

For MileagePlus frequent flyer account questions, call 1-800-575-2929. This line handles mile redemptions, account status, elite benefits, and questions about your rewards balance.

What to have ready before you call

United will ask for your confirmation number first — this is the six-character code in your booking confirmation email. If you do not have it, have your ticket number or the name and date of birth on the reservation ready instead. The representative can pull up your account with any of these pieces of information.

For baggage claims, have your baggage tag number and the flight number from the day your bag was lost or delayed. For refund requests, have the original booking confirmation and the reason you are requesting the refund. For MileagePlus questions, have your frequent flyer number, which appears on your boarding pass and in your account online.

Write down the date and time you call and the name of the representative you speak with. If you need to follow up or dispute something later, this information helps United locate your case in their system.

When phone lines are busiest

United's phone lines are heaviest during the hours when ready after a major flight disruption — cancellations, severe weather, or system outages. If a widespread issue has just occurred, you may wait 45 minutes to over an hour. Calling the next day, once the when ready crisis has passed, usually results in a much shorter wait.

Holidays and peak travel seasons (Thanksgiving week, Christmas week, spring break, and summer) see higher call volumes across all lines. If your issue is not urgent, waiting until after the peak period reduces your hold time significantly.

The reservations line is busiest on Tuesday through Thursday mornings, when people book weekend trips. The baggage line is busiest in the evening, when travelers have just arrived and discovered a missing bag. The refunds line is busiest in the days when ready after a major cancellation event.

Alternatives to calling

United offers other ways to reach customer service that sometimes have shorter wait times than the phone. You can message United through their website at united.com by clicking "Contact Us" at the bottom of the page, then selecting "Chat" or "Email". Chat responses typically come within a few hours during business hours, and email responses within 24 to 48 hours.

The United mobile app also has a "Contact Us" option that lets you message customer service directly. Responses through the app follow the same timeline as the website.

For straightforward changes — seat selection, adding a checked bag, or viewing your itinerary — you can make these changes yourself on united.com or in the mobile app without calling. This is often faster than waiting on hold, especially for routine requests.

International calling and TTY service

If you are calling from outside the United States, United has regional phone numbers. From Canada, call 1-800-538-2929. From the United Kingdom, call 0808-238-5000. From other countries, visit united.com and select your country to find the local number.

Frequently Asked Questions

How long will I wait on hold when I call United?

Can I schedule a callback instead of waiting on hold?
