SECTION 3 — How to Change or Correct a Name on a United Airlines Ticket

A name on your airline ticket must match your government-issued identification exactly. Even a small typo can prevent you from boarding. United Airlines has a clearly defined name correction policy that distinguishes between minor corrections and full legal name changes.

Minor Name Corrections

A minor name correction typically involves fixing a typo, transposed letters, or a missing middle name. United Airlines allows minor corrections of up to 3 characters for most fare types. These corrections can usually be made without a fee if caught early.

To request a minor name correction, call United Airlines at 1-866-284-3014 and have your booking confirmation number and the correct spelling of your name (as shown on your ID) ready.

Legal Name Changes

A legal name change — for example, after marriage or divorce — requires documentation such as a marriage certificate or court order. United Airlines will update your ticket name to reflect your legal name, but the corrected name must exactly match the name on your new government-issued ID.

Step-by-Step: How to Correct Your Name on a United Airlines Ticket

Gather your booking confirmation number and the misspelled name on the ticket.
Locate your government-issued ID showing the correct name.
Call United Airlines at 1-866-284-3014 and explain you need a name correction.
Provide the agent with your booking reference and the correct spelling.
If a legal name change, submit the required documentation as requested by the agent.
Confirm the corrected itinerary and check that the new name appears correctly on your updated booking confirmation.

Important: United Airlines does not allow full passenger name transfers (i.e., completely changing the passenger to a different person). Name changes are limited to corrections or legal name updates. If you need to transfer a ticket to someone else, you will need to cancel and rebook.

Name Correction for International Flights

For international travel, name accuracy is even more critical because it affects visa and passport verification. If you discover a name error on an international booking, call 1-866-284-3014 immediately. Do not wait until the day of departure.
