First, I'd like to say that I have NEVER received poor treatment or rude service from agents non-revving on American. On the contrary, most of the agents are extremely helpful anytime a problem arises.
As for posting lists, I think that the best thing in the world to a non-rev is Delta's new Gate Information Display System. The system, which places monitors around gates at the airport, is currently in place in a handful of locations and is being expanded. The screens show a variety of flight information, such as meal services, weather, aircraft layout, etc. Three screens, however, are key to the non-rev... The first is a simple booking screen, listing how many people are booked in each cabin, how many have actually checked in for each cabin, and how many seats are available in each cabin. The second is a screen that is a continuously updated standby list. Every time a new passenger checks in non-rev, their position on the list is determined and the list shows the appropriate order. You can always see where you stand, and the system does not reveal pass priority or anything; it only tells the number of people in the party, a few letters of the last name, and the first initial. Finally, a similar screen gives the revenue upgrade priority list, which, along with the availability screen, tells non-revs whether there will be any First Class seats available after the Madallion upgrades are processed.
