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 MileagePlus 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 MileagePlus 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 MileagePlus is Saturday. The most busy day to call is Thursday, which averages 60% more phone calls by comparison. Again, this is based on a sample of 800 calls made with our AI-powered, web-based phone in the last 90 days.

But if you use our free call and talk for me or wait on hold for me service, you don't really need to worry about average wait times.
