flaps:
Condor has operated one of their B-757-300 on the FRA-MUC route, but no results were published. I am certain that with no ULDs, only one aisle and at most airports, only one door used, this is not a perfect fit for the high frequency short turn-around trips, but which aircraft is there today on the marked?
For the time being, LH have converted the medium-haul A300-600 to short haul and have added one bought from Emirates second hand.
