The main United MileagePlus phone number and what it covers

United Airlines' main MileagePlus customer service line is 1-800-241-6522. This number handles account questions, mileage transfers, redemptions, and general program inquiries. Wait times vary by time of day and season, but calling early in the morning on a weekday typically means shorter holds than calling in the afternoon or on weekends.

The line is staffed Monday through Friday from 6 a.m. to midnight Central Time, and Saturday and Sunday from 7 a.m. to 11 p.m. Central Time. If you call outside these hours, you can leave a message and a representative will return your call, though response times may be longer during off-peak periods.

Have your MileagePlus account number or the email address associated with your account ready before you call. This speeds up verification and gets you to the right department faster. If you are calling about a specific flight or reservation, have your confirmation number available as well.

Key Takeaways

  • The main MileagePlus phone number is 1-800-241-6522, available Monday through Friday 6 a.m. to midnight Central Time and weekends 7 a.m. to 11 p.m. Central Time.
  • Have your MileagePlus account number or registered email address ready before calling to speed up the verification process.
  • Different issues route to different departments, so being specific about your question when prompted helps reach the right team faster.
  • The online MileagePlus website and mobile app can handle many routine tasks like checking balances, transferring miles, and viewing account details without waiting on the phone.

What you can handle online instead of calling

Many MileagePlus tasks do not require a phone call. You can log into your account at mileageplus.united.com or use the United mobile app to check your current mileage balance, view your account details, transfer miles to another member, and see your account history. These functions are available 24 hours a day and take just a few minutes.

You can also book award flights online, manage your seat selections, add or remove companions on award tickets, and view your elite status benefits without calling. If you know exactly what you need and your account is in good standing, the website is usually faster than waiting on hold.

The mobile app also lets you receive notifications about your miles expiring, special promotions, and account activity. Setting up these alerts can help you avoid losing miles to inactivity, which is one of the most common reasons members call customer service.

Specific phone numbers for different MileagePlus issues

While 1-800-241-6522 is the main line, United routes callers to different departments based on what you need. When you call, the automated system will ask you to describe your issue or press a number for your topic. Being specific helps you reach the right team without transferring multiple times.

If you are calling about a credit card linked to your MileagePlus account, you may be routed to the card issuer's customer service line instead of United directly. Chase issues the United MileagePlus credit card, so card-specific questions sometimes go to Chase at 1-800-935-9935, though the main United number can also help with card-related account questions.

For issues with award bookings, mileage transfers, or account access, stay on the main line. The system will route you appropriately once you describe your issue. If you are transferred and end up with the wrong department, ask to be transferred back to MileagePlus customer service rather than hanging up and calling again.

Wait times and the best times to call

MileagePlus customer service lines experience heavy call volume during certain times. Early morning calls on weekdays—between 6 a.m. and 9 a.m. Central Time—typically have the shortest wait times. Mid-morning and early afternoon tend to be busier, and evenings and weekends can have longer holds as well.

Avoid calling on Mondays if possible, as that is when weekend account issues and travel problems accumulate. Tuesday through Thursday mornings are usually your best bet. If you have a non-urgent question, calling during these windows can save you 15 to 30 minutes of hold time.

During major travel periods—holidays, spring break, and summer vacation weeks—all customer service lines experience increased volume. If your question is not time-sensitive, waiting until after these peak periods can mean shorter waits and faster service.

What to do if you cannot reach someone by phone

If you have been on hold for an extended time or prefer not to call, United offers other ways to contact MileagePlus support. You can send a message through your MileagePlus account on the website by logging in and selecting "Contact Us." Response times for email inquiries are typically 24 to 48 hours, though they can be longer during peak travel periods.

The United mobile app also has a "Contact Us" feature that lets you submit questions directly. Some issues can be resolved faster through the app than through email because the system can pull your account information automatically.

United also maintains a social media presence on Twitter and Facebook where you can send direct messages about account issues. Response times on social media are often faster than email, sometimes within a few hours during business hours. Tag @United or @MileagePlus in your message to reach the right team.

International calling and account access from outside the US

If you are calling from outside the United States, you can reach MileagePlus customer service at the international number +1-847-700-3000. This is a direct line that bypasses the automated system, though wait times may be longer and international calling charges explore depending on your phone plan.

Your MileagePlus account is accessible from anywhere in the world through the website and mobile app, so you can manage your account online without making an international call. The website and app work the same way whether you are in the US or abroad.

If you are a frequent international traveler, consider setting up your account preferences online before you travel. You can add trusted devices, set up two-factor authentication, and update your contact information so you do not need to call customer service while traveling.

Common reasons people call and how to prepare

The most frequent MileagePlus calls involve checking mileage balances, redeeming miles for flights, transferring miles to another member, and resolving account access issues. Before you call, know which of these applies to you so you can answer the automated system's questions quickly.

If you are calling about a specific flight or award booking, have your confirmation number, flight dates, and passenger names ready. If you are calling about a mileage transfer, have the recipient's MileagePlus account number and full name. If you are locked out of your account, have your email address and a form of ID ready to verify your identity.

Write down your main question before calling so you do not forget it while on hold. If the representative transfers you, you can reference your notes to explain the issue again quickly rather than repeating the entire story.
