The aircraft was a long haul configured 767 and it was still sitting forlornly on the snow covered tarmac at GVA this morning when I finally got out on another flight.

The fact that a long haul 767 was operating on the GVA route probably means they don't have many knocking around at the moment so maybe it's had an effect on other 767 rotations (e.g. the DUS plane being "stolen" for another route).
