I ordered DC8 51-53's finding that they would not be allowed to be scheduled between even major cities!
Pairing cities with 12,000ft and a DC8 needing under 9000, with a low de luxe seating arrangement, they are refused to be scheduled.
Same with B707 120 / 320c Aircraft.
This despite some reaching a 4,700 miles + capability.
Eg MEB-HND. or via CMB to LHR?
Seems to be a systemic problem, and two types of modern Aircraft cannot be used as a result!
Any analysis pls?
