9E jumpseat has always been good to me. I once had a captain on 9E fly at a lower altitude to burn off fuel because of a landing weight issue, just so I could get on. This same captain was in the jumpseat on our flight on my next trip, and i turned down a meal so he could eat instead.
Most try to get numbers to work but sometimes its just not going to happen as we are just trying to get down to weight with the pax in the back!
