What are United MileagePlus customer service hours?

Their main phone line is open from 7:00 a.m. to midnight, Central Time. So, if you're on the West Coast, you can call pretty late. Just don't try calling at 3 a.m. unless you enjoy hold music.

Is there a United MileagePlus live chat option?

Yes, but it's a bot first. You have to fight with it a bit. It's on their website and in the app, but be prepared to type "speak to an agent" a few times before it gives up and connects you to a real person who is probably handling ten other chats at once.

What's the fastest way to reach United MileagePlus support?

Phone. Just call. If you have Premier status, use that special number they give you because it genuinely cuts the wait time in half, otherwise, you're stuck in the general queue with everyone else trying to figure out why their miles from a flight to Cleveland six months ago never posted. The online forms are a black hole.

Do I need my account number to contact United MileagePlus?

Yes. Absolutely. Don't even bother calling without it. It's the first thing they'll ask for.

Can I email United MileagePlus customer service?

Not really. They don't have a public support email because they'd rather you use their complicated online contact form, which feels like sending a message in a bottle and hoping it washes up on the right shore in a week or two. Good luck with that.

Is there a United MileagePlus mobile app for support?

The main United Airlines app is what you'll use. It has a "Contact Us" section buried in the menu. It basically just gives you the same phone numbers and a link to the chat bot. It's not a magic bullet, but it's convenient if you're already in the app checking on a flight.

What information should I have ready when calling?

Your MileagePlus number, for sure. Have it all ready. You need your MileagePlus number, the full names of any passengers involved, and if it's about a specific trip, the six-character confirmation code, because the agent isn't a mind reader and they won't want to spend ten minutes while you dig through your inbox for an email from last March.

How do I complain to get compensation or miles?

Use the online feedback form, not the phone. You want a paper trail. Be polite but firm, list exactly what went wrong, like 'in-flight entertainment broken on a 6-hour flight' or '2-hour tarmac delay', and state what you want. Don't just say 'compensate me.' Ask for a specific number of miles, like 10,000. They're more likely to give you something if you make a reasonable ask.

How to Contact United MileagePlus Customer Service

Trying to reach United MileagePlus support feels like trying to upgrade to Polaris with a basic economy ticket. You are definitely not alone if you are frustrated. Whether you are dealing with missing miles that never posted, trying to figure out the new family pooling feature everyone is talking about on TikTok, or just locked out of your account, we have the details. Common headaches reported on Trustpilot include billing disputes, trouble booking award travel, and technical glitches with the app. You can reach them via 1-800-421-4655, their "Agent on Demand" chat, or through the United MileagePlus website. Here is how to actually get through to a human without losing your mind.

Customer Support Channels

📞 Phone Support

If you need to talk to someone, pick the right number. The general reservation line often cannot help with specific account issues.

Department	Phone Number	Hours (CT)
MileagePlus Service Center	1-800-421-4655	7:00 am – 12:00 am
General Reservations	1-800-864-8331	24/7
Accessibility Desk	1-800-228-2744	24/7

📧 Email & Form Support

Direct email addresses for United are notoriously unreliable and often bounce back with auto-replies. Use the forms instead.

Purpose	Method	Notes
Missing Miles	Request Form	Have your ticket number (starts with 016) ready
Status Match	Status Match Form	Takes 7-14 business days
General Feedback	Customer Care Form	Best for formal complaints

💬 Live Chat (Agent on Demand)

Where to access: United App (under "More" > "Contact us") or scanning QR codes at the airport.
Steps: Open the app, type "Agent", and request a human.
Best for: Rebooking cancelled flights or simple policy questions.
Note: The bot is pretty basic. Type "Representative" immediately to skip the loop.

📱 In-App Support

Platform: iOS and Android
How to use: Go to the Help Center within the app. You can start a chat or find click-to-call buttons that sometimes bypass the main IVR menu.

Estimated Response Times from United MileagePlus

Method	Expected Wait Time
Phone (General)	30–60 minutes (Mondays are worst)
Phone (Premier Line)	< 5 minutes (Status holders only)
Chat	10–20 minutes
Online Forms	7–10 business days
Social Media (X)	1–3 hours

Tips to Reach Support Faster from United MileagePlus

Call mid-week: Tuesdays and Wednesdays between 2 PM and 4 PM CT usually have lower call volumes.
Use the "Premier" trick: If you have Silver status or higher, ensure your phone number is linked to your account. The system recognizes it and routes you to a faster queue automatically.
Try the foreign numbers: Weirdly, calling a United international support number (like the UK line) can sometimes get you to an English-speaking agent faster than the US line.
Social Media DM: Send a Direct Message on X (Twitter). The social team often responds faster than the email team.

Before You Call: What to Have Ready

Don't waste your time. Before you call, make sure you have your account number and the email you signed up with handy. Trust me, they will ask for it immediately.

Your MileagePlus Number: Memorize it or have it on a sticky note.
Ticket Number: This is the long number starting with 016. The confirmation code (e.g., ABC123) isn't always enough for missing miles.
Flight Dates and Numbers: If you are claiming missing credit, you need the exact flight number.
Partner Airline Info: If you flew Star Alliance (like Lufthansa or ANA), have their ticket receipt ready too.

Where to Quickly Solve Problems with United MileagePlus

If Your Problem Is...	The Best Contact Method Is...	Pro Tip
Missing Miles	Online Request Form	Phone agents usually just tell you to fill out this form anyway.
Booking an Award Ticket	Phone (1-800-421-4655)	The website glitches often on complex itineraries. Call to lock it in.
Name Change	Upload Documents Online	You cannot do this over the phone. You need to upload a marriage cert or ID.
Billing/Refunds	Refunds Page	Check status online before calling. It saves you 20 minutes of hold music.
