Different Ways to contact MileagePlus
Customer Support Channels
📞 Phone Support
Getting a human on the line is often the goal. Be prepared for a wait, especially during peak travel seasons. If you have Premier status, use the dedicated number on the back of your card for a much shorter queue.
| Department | Phone Number | Hours (Central Time) |
|---|---|---|
| MileagePlus Service Center | 1-800-864-8331 | 7:00 a.m. – 12:00 a.m. (midnight) |
| Premier Priority Desk | Check the back of your membership card | 24/7 for Premier 1K members |
📧 Email Support
MileagePlus doesn't really do traditional email. Instead, they funnel everything through a contact form on the United website. It's a bit of a maze to find, but it gets the job done for non-urgent stuff.
| Purpose | Link / Method | Notes |
|---|---|---|
| General Inquiries & Feedback | United Customer Care Form | Response can take several business days. Good for creating a paper trail. |
| Missing Mileage Credit | Request Mileage Credit Form | Have your ticket number handy. This is way faster than calling for this specific issue. |
💬 Live Chat or Website Bot
The chat feature is your best bet for avoiding phone hold music. It starts with a bot, but you can get to a human.
- Where to access: Log in to your MileagePlus account on United.com or use the United mobile app.
- Steps to access: Look for the chat icon, usually at the bottom right of the screen or in the 'Contact Us' section of the app.
- What it handles: Good for flight information, simple booking questions, and website navigation issues.
- Escalation: If the bot can't help, you can type "speak to an agent" to get transferred to a live person. Sometimes this takes a minute.
📱 In-App Support
The United app is surprisingly useful for more than just your boarding pass.
- Platform: Available for iOS and Android.
- Steps to contact: In the app, navigate to the 'More' tab, then find the 'Contact Us' section. This usually provides shortcuts to call or start a chat.
Estimated Response Times from MileagePlus
| Method | Expected Wait Time |
|---|---|
| Phone | 15 - 90+ minutes (highly variable) |
| Online Contact Form | 3 - 10 business days |
| Live Chat | 5 - 30 minutes |
| In-App Support | Varies (chat is usually fastest) |
Tips to Reach Support Faster from MileagePlus
- Call during off-peak hours. Try calling mid-week (Tuesday-Thursday) either right when they open or later in the evening. Avoid Mondays and Fridays.
- Use your Premier status. If you have any level of elite status, always use the dedicated phone number on your card. It's a completely different, and much faster, queue.
- Try the chat first. For simple questions, the live chat is almost always quicker than waiting on hold.
- Have your info ready. Don't make them wait while you search for your MileagePlus number or flight confirmation. More on this below.
- Use social media as a last resort. Sometimes, a public post to United on X (formerly Twitter) can get a faster response for certain issues, but it's not a guarantee.
Before You Call: What to Have Ready
Seriously, don't waste your own time. Before you even dial, get your stuff together. The agent will thank you, and you'll get your problem solved way faster.
- Your MileagePlus number. This is the absolute first thing they will ask for. Have it copied and ready to paste or read out.
- Flight confirmation numbers or ticket numbers. If your issue is about a specific flight, past or future, have the 6-character confirmation code or the 13-digit ticket number.
- The email address and phone number on your account. They use this for verification. Make sure it's the one you actually signed up with.
- A brief, clear summary of your problem. Know what you need to ask before they pick up. Rambling will just confuse things and prolong the call.
Where to Quickly Solve Problems with MileagePlus
| If Your Problem Is... | The Best Contact Method Is... | Pro Tip |
|---|---|---|
| Missing miles from a flight | Online Request Form | This is an automated process. Calling will just have the agent fill out the same form for you, but slower. |
| An urgent booking change (within 24 hours) | Phone Support (1-800-864-8331) | Phone agents have the most power to make immediate changes or waive fees. Don't use the form for this. |
| Your account is locked | Phone Support | For security reasons, you'll almost always need to verify your identity over the phone to unlock an account. |
| A technical glitch on the website | Live Chat | It's easier to explain a tech issue via chat, and you can send screenshots if needed. |
| Filing a formal complaint | Online Contact Form | This creates a written record that gets routed to the right department. Be specific and include dates, flight numbers, and names. |
