Mistakes happen, but United Airlines name change policy ensures passengers can correct errors with ease. If your ticket has a minor typo—such as a misspelled first or last name—you can update up to three characters online for free. However, if you need a change name on United Airlines ticket due to marriage, divorce, or a legal name update, you must provide official documentation like a marriage certificate or court order. These changes cannot be made online and require contacting United Airlines customer support. https://www.flightpolicyhub.com/blog/united-airlines-name-change-policy
