How do I get through the phone menu to a real live person?

GetHuman researchers routinely call this United Airlines phone number to document the phone system.
Here is our latest tip for weaving through the phone menu to get to a real person the fastest: Calling this United Airlines number should go right to a real human being
In fact, much of this information on this page is superfluous because this United Airlines phone number is a direct line to a human being. The line is well-staffed and you should anticipate a very short wait on hold or none whatsoever, as long as you are calling during business hours.
We don't know of any phone menus you would encounter when calling either.

What are the hours and when should I call?

United Airlines operates the call center for this 312-364-1989 phone number 24 hours, 7 days. The short answer is that you should call on a Monday. This observation and the following section are based on analysis of a sample set of 36,443 calls made in the last 90 days using our free, web-based phone (see above).
An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this United Airlines phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like United Airlines staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy time to call

The least busy day to call United Airlines is Monday. The most busy day to call is Wednesday. Again, this is based on a sample of 36,443 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Friday. The longest wait in the queue on average occurs on Wednesday.

The best time to call

In summation, the best day to call United Airlines is Monday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that United Airlines staffs the call center well on Monday.
Once again, please put this information in perspective because this phone number has no phone menu or long waits. It generally gets picked up right away if calling during their opening hours. If there is any way, it will typically be very short.

Calling this United Airlines Customer Number

I'm not very Internet savvy, so when it came time to book a flight for the holidays, I decided to call United Airlines directly to do it. I know there is a booking fee if you call them, but I'm willing to pay it so that I can talk to someone and make sure I am booking exactly what I want. There was an automated system I had to get through first to talk to someone, but it was easy enough to follow. 

I was actually surprised by how quickly I was able to get to an agent. People might need to call United Airlines for thousands of reasons, from help with lost luggage to booking flights, checking on flight status or attempting to change flights. Daily, there are probably hundreds of flights that take off across the United States, so I thought the response time was pretty decent. 

When I called, the automated agent said, "Thanks for calling United Airlines. How can I help you? Please say in a few words why you are calling us today. You can say things like, I'd like to make a reservation or I'd like to change my flight."

I said, "Book a flight," and then it stated, "Let me get some information about your trip, and I'll transfer you to an agent to book your trip. Please be aware you can skip the booking fee by going online. What city are you departing from?"

I told him Cleveland, and then it repeated back to me to ensure I was right. It then asked about my destination, and I said LA. It then asked, "What day would you like to depart? You can also say, I'm not sure."

I told the agent Monday, December 18th, and then it told me politely that "we are almost done" and asked how many travelers there were. Immediately after that, it told me that it was going to transfer me to an agent, and then I had to listen to the privacy policy. 

Before talking to the agent it asked me if I was planning to use travel miles or certificates and if I would like to participate in a brief survey. About three minutes into the phone call, an agent picked up right after the survey request. He had a very thick accent, and at times, it was hard to understand what he was saying, but eventually, I was able to book my flight.
