Customer Support Channels

📞 Phone Support

Getting a human on the phone is often the most direct way to solve a problem with MileagePlus. Be prepared for potential wait times, especially during peak hours.

Department Phone Number Hours (Timezone)
MileagePlus Service Center 1-800-421-4655 24 hours a day, 7 days a week
Premier Priority Desk (for elite status members) Check the back of your membership card 24 hours a day, 7 days a week
United Customer Care 1-800-864-8331 24 hours a day, 7 days a week

💻 Online Contact Form

MileagePlus doesn't offer a direct support email address. Instead, they use a structured contact form on the United website. This is your best bet for creating a digital paper trail.

  • Where to access: United's Contact Us Page
  • Steps to access: Navigate to the page, select the topic that best fits your issue (e.g., 'MileagePlus inquiry'), and fill out the required fields.
  • Types of problems it handles: Missing miles, account questions, feedback, and complaints.

💬 Live Chat or Website Bot

MileagePlus does not currently offer a dedicated live chat feature for general customer service inquiries. The chat function on the United website is primarily focused on booking new flights and is often handled by a bot that can't access detailed account information.

📱 In-App Support

The United Airlines app (for iOS and Android) is the main hub for your MileagePlus account. While it doesn't have a dedicated 'contact support' chat feature, you can use it to manage your account, find your MileagePlus number, and access the mobile website to find contact forms.

  • Platform: iOS and Android
  • Steps: Download the United app, log in to your MileagePlus account. Most service options will redirect you to the website or provide a phone number.

Estimated Response Times from MileagePlus

Method Expected Wait Time
Phone 5 minutes - 1 hour+ (highly variable)
Online Contact Form 2 - 10 business days
Mail 2 - 4 weeks
App N/A (redirects to other methods)

Tips to Reach Support Faster from MileagePlus

  • Call at off-peak times: Try calling late at night or early in the morning (U.S. time) to avoid long hold times.
  • Use your Premier status: If you have elite status, make sure to call the dedicated Premier Priority Desk number. The wait times are almost always shorter.
  • Have your info ready: Don't waste time searching for your MileagePlus number or flight details while you're on the phone. See the list below.
  • Try the website first: For simple things like requesting missing miles from a United flight, the online form is actually faster than calling.

Before You Call: What to Have Ready

Seriously, don't call until you have these things in front of you. The agent will ask, and it's just awkward fumbling around for them while on the phone. Trust me on this.

  • Your MileagePlus Number: This is the absolute first thing they'll ask for. It's in the app and on your emails.
  • Flight Details (if applicable): Have your confirmation number, ticket number, flight numbers, and dates ready.
  • The Email Address on Your Account: They use this for verification.
  • A Pen and Paper: You'll want to write down the agent's name and any reference number they give you, especially for a complaint.

Where to Quickly Solve Problems with MileagePlus

If Your Problem Is... The Best Contact Method Is... Pro Tip
Requesting Missing Miles Online Form This is automated for United flights and usually credits within 48 hours. It's much faster than calling.
Booking a Complex Award Flight Phone Support (1-800-421-4655) Agents can see partner airline availability that sometimes doesn't show up online. Be specific about your desired routes.
A Password Reset Website Self-Service Don't call for this. The 'Forgot Password' link is the quickest way, period.
Filing a Formal Complaint Online Contact Form This creates a written record with a case number that you can reference later. Phone calls work, but a paper trail is better.
