I was just curious about different airlines and how they staff agents for flights. I know there is a large gate agent/ CSA group on a.net so hopefully I can get a broad range of perspectives from different carriers.

I was once an agent for a regional airline before becomming a flight attendant, and it wasn't a complicated process too often. Each flight involved had one agent for boarding and our responsibilities were rather limited. We would meet the flights, deplane, board, ensure the outbound crew recieved a release, pre board, board, close the flight and ensure all the paper work was put together- which was the release, and a outbound pax list.

I however often observe the larger carriers and have noticed they often have more agents, which makes sense as they have additional passengers- I've observed DL 757s with five agents working them. I am also currious if companies like UA, DL...etc have their agents assigned to more duties and responsibilites on the gate such as weight and balance, catering...etc?
