Are name changes allowed? Generally, only minor name changes or corrections are allowed, such as fixing a typo or updating the ticket to reflect a legal name change (e.g. last name change through marriage). Name changes to transfer flight tickets are generally not allowed for a few reasons.

Changing a passenger's name after checking in is exceptionally difficult and often impossible without canceling the check-in and potentially the entire ticket. Once you have checked in, your "Advanced Passenger Information" (API) is typically transmitted to government security agencies and the flight manifest is finalized. Most airlines allow for minor typo corrections (1–3 letters) free of charge or for a small fee before check-in, but a full name transfer to a different person is prohibited by almost all major carriers due to security and anti-fraud regulations. If you realize there is a major error after checking in, you must immediately contact the airline's customer service. They may be able to "un-check" you, correct the name (if it's a legal change like marriage or a typo), and have you re-check in. If you are trying to give your ticket to a friend, you will likely find that the airline requires you to cancel the booking and purchase a new one at current market prices.
