Customer Support Channels

📞 Phone Support

United's main phone line is open 24/7, but be prepared for potentially long wait times during peak travel seasons. It's a bit of a lottery.

Department Phone Number Hours (ET)
Reservations (U.S. & Canada) 1-800-864-8331 24/7
MileagePlus Service Center 1-800-421-4655 8:00 AM - 12:00 AM (Midnight), Daily
Baggage Resolution Center 1-800-335-2247 8:00 AM - 12:00 AM (Midnight), Daily
Disability Assistance 1-800-228-2744 24/7

📧 Email Support

United doesn't offer a direct customer service email address. Instead, they use a series of online forms for feedback and complaints. This creates a ticket, but responses can be slow.

Purpose Link / Method Notes
General Complaints & Feedback Customer Care Form Response can take several business days. Good for creating a paper trail.
Refund Requests Refunds Page Use this for eligible cancellations and refund inquiries.

💬 Live Chat or Website Bot

United's chat is available on their website and is often the fastest way to get simple answers.

  • Where to access: Click the "Help" or chat bubble icon on the bottom right of the United Airlines website or find it in the app's contact section.
  • Steps to access: You'll start by talking to an automated assistant. It can handle basic queries like flight status or baggage allowance.
  • Types of problems it handles: Best for simple questions, finding information, and minor booking assistance.
  • Escalation: If the bot can't help, you can type "talk to an agent" to be transferred to a live person. The wait for a human can vary.

📱 In-App Support

Using the United app is probably the most convenient method for on-the-go support.

  • Platform: Available for iOS and Android.
  • Steps to contact support: In the app, navigate to the "More" tab, then select "Contact Us." From there, you can access the messaging feature, which is the same as the website's live chat. You can also find phone numbers and a link to the help center.

Estimated Response Times from United Airlines

Method Expected Wait Time
Phone 5 minutes - 2+ hours (highly variable)
Online Form (Email) 3 - 10 business days
Live Chat / Messaging 2 - 30 minutes
Social Media (X) 1 - 6 hours

Tips to Reach Support Faster from United Airlines

  • Call during off-peak hours: Try calling late at night or early in the morning (U.S. time) to avoid the longest queues.
  • Use the app's chat feature: For non-urgent questions, the in-app messaging is often much faster than waiting on hold.
  • Leverage elite status: If you have Premier status with MileagePlus, use the dedicated phone number on the back of your card for shorter wait times.
  • Try the callback feature: If offered during a high-volume call period, always select the option for an agent to call you back. It saves you from sitting on hold.
  • Be persistent with the chat bot: If the automated assistant isn't helping, repeatedly type "agent" or "representative" to get transferred to a human.

Before You Call: What to Have Ready

Don't waste your own time. Before you even think about dialing, get your information together. Trust me, the agent will ask for it, and fumbling for a confirmation number while you're on the line is just stressful for everyone.

  • Your 6-digit confirmation number: This is for your specific flight booking. It's in your confirmation email.
  • Your MileagePlus number: If the inquiry is related to your account, have this ready.
  • Flight details: Know the exact flight numbers, dates, and cities you're calling about.
  • The credit card used for booking: They may ask for the last four digits to verify your identity.
