Check the website for the airline you will be flying on to find out its policies about boarding passes. Most airlines do not allow you to transfer tickets from one passenger to another. Jonella J. Culmer of the Transportation Security Administration said that her agency accepts ticket transfers up until the last minute. But the airlines don't. So If you can't make the trip and have to send a family member or colleague instead, you will have to buy a new ticket. If you bought a more expensive, refundable ticket, this may be no big deal. If you bought the cheaper, non-refundable kind, you may be in for some big fees.
Change your information on your airline rewards plan, if you have one. If you book through one of these or a travel service, changing the information will alter the information on the boarding pass. Sometimes you can do this online but if it is a significant change, you may have to mail or fax documentation, such as a marriage license, that shows the names change. If you don't have time, take the marriage license and old and new I.D.'s with you to the airport and check in early.
Don't worry about small differences such as a middle name that doesn't match your I.D. While it's easiest to check in with all matching identification, the Transportation Security Administration can run a check in minutes to clear you for your flight.
Call the airline for exceptions. For example, Southwest Airlines has a companion pass that travelers can change as often as three times in a year. But the request to change must be made in writing, and must include all security information required by the T.S.A. It also takes 21 days for processing.
