That is a great PDF link. The instructions seem comprehensive. I don't see this program lasting -- too many details to remember and I bet most people will have their P.A. or assistant deal with this.
It is nice you can use it for friends and relatives for arrivals even though you are not there -- an escort at the airport to make the airport to home trip smoother.
The big benefit of course is the escort to the Admirals Club -- even when not a member.
This could be very useful during the holiday periods -- like the busiest travel day of the year.
