Try self-service first
The United app handles rebooking during irregular operations unusually well — when a flight cancels it will often present alternatives before an agent can. Use it first.
Phone support
United publishes reservation numbers by region on united.com/contact. Premier lines are separate. During mass disruption the app and Twitter beat the phone queue substantially.
Chat and messaging
Automated and live chat both run inside the United app. Live agent handoff is available once the bot cannot resolve the request.
Social and in-app support
@united on X is staffed and responsive. The app also offers an "Agent on Demand" video/text queue at many hub airports, which is faster than the physical customer service line.
Escalating a complaint
Submit a complaint via united.com/customercare. Unresolved matters can be filed with the US DOT Aviation Consumer Protection Division.
Your refund rights
If United cancels or significantly changes your flight and you decline the alternative, DOT rules entitle you to an automatic cash refund rather than a credit. United must issue it without you asking.
