DSA-NQY
Sitting back and thinking about this, its really not a bad idea I wouldn't of thought.
NQY has a long history of doing well on routes into this general area with BMIbaby and AirSouthwest, I cant recall DSA operating but MAN has and still does attract good numbers, EMA and LBA have previously sustained 737 or multi day DH8-300 rotations.
In the fullness of time I could see DSA running alongside LBA and MAN and quite possibly EMA into NQY.
Apart from that, as others have pointed out this ties up an aircraft which seems quite well used apart from these 3 time slots, which from DSA and the spare time that the aircraft has limits the options for a fill in route !
