An A330 will be too expensive to operate on short haul sectors imho...
Average flight time of an "express freight" cargo aircraft in europe is what, around 4 or 5 hours ?
A bit a waste of money letting it sit on the ground for 3/4th of the day.
Plus indeed the slope comes to mind as being (although a fixable) problem.
The payload is also too much , the only thing which comes to mind being useful is the volume you can ship...
They should start on those conversions of the Luftie A300's... when this crisis is over in 10 years or so they can use them ;-)
