I'm going to be taking an elderly family member to the airport soon and was wondering how to go about getting a gate pass so that I can escort her to the boarding area. There's also a good chance she'll be using a wheelchair to get there so there will be an airport employee taking her through security but then they'll just leave her. I was hoping to keep her company until boarding time.

Can anyone provide insight on the procedures for getting a pass? Do I have to apply for it ahead of time or when I take her to the airport? Do I need to take some particular type of ID? Is this a generally tedious process or will it likely be a simple request?....

Thanks.
