United Customer Contact Center
If you’d like to buy a ticket or change existing reservations or tickets, start by choosing your current location from the list below.
You can always purchase tickets without a service charge on united.com. To book with a United representative in the United States or Canada, the service charges are $25 by phone, $10 at a City Ticket Office and $50 at the airport. Ticketing charges may vary outside of the U.S. and Canada and based on your MileagePlus status level.
You can change or update existing reservations in the My trips section of united.com or the United app. There’s no service charge to get help from our Customer Contact Center by phone if you have an existing reservation, but your representative will inform you of any change fees that may apply.
