The name on the ticket should be accurate, according to every airline. The United Airlines Name Change Policy was thus developed as a solution to this situation by United Airlines. When you adhere to this policy, your trip will go smoothly and there won't be any problems when you head out to catch your aircraft. In light of this, frequent travellers should be informed of United Airlines' policy regarding name changes.

The United Airlines name change policy is explained in detail here. Quickly scan it, then make sure your name is spelt similarly to how it appears on your passport and on the ticket.
