June 2004, flying FCO-FRA-IAD on LH/UA.
Check-in at FCO, given a boarding pass and then a gate pass at FRA for my seat to be assigned at FRA.
Land in FRA, kill some time, go to the gate and am told to wait for my name to be called. They start calling names. Everyone but 1-2 people have boarded and I'm called. Seat was something like "14C." I took the boarding pass and as I boarded the plane I thought to myself "this is awfully far to the front..." when I stumbled onto my seat which was in J.
Was a student and originally booked in a cheapie Y seat, but was LH Silver at the time. First op-up and first time in J.
