On United it should show your priority on your DM Card. If your a UAL mainline employee you should have BP8A (Boarding Priority 8A). Employee of a UAL partner: usually BP8C. I really depends on your benefits and you contract between your airline and the one your flying on. I've seen employees of other carriers fly on United under BP9 status... i.e.- not good. No matter what, always list for first class, that way you at least have a shot at sitting in the nice seats.
