Couple of months ago I was non-revving AB) (FRA / FRF / EDDF), Germany">FRA to the US.
As my train arrived there around mid-day the only flight possible was ORD on a 763 which was overbooked. They were offering up-grades from coach to business and first for a couple of hundred. Obviously I did not make that flight and had to spend a night there and try the next morning to DFW. When I got there the second day they were offering upgrades again on both DFW & ORD flights... I managed to get on the DFW flight on board a 777.
Couple of months later I've heard the same stories from some friends always on the ORD flight.. So my question: is why not upgrade AB) (FRA / FRF / EDDF), Germany">FRA-ORD to a 777 or have more flights from out there? I remember seeing many UAL 777's like 4 or 5 but I know they have the LH codeshare there...
