fwiw...i ride ual mainline A LOT when i commute (i just started commuting 3-4 months ago). i never list on expressnet 1st, just go up to the gate and request to list for the jumpseat. i have yet to ride in the actual jumpseat, they always give me a seat in the back, and I have not been charged for anything. i certainly hope it stays that way. if they start charging for cabin seat when we are omc's then they are gonna have to allow us in the cockpit even when there are open seats in the back.
