pzu - On reading your post I momentarily thought you may still be in Africa !!
DTV only has two schedules! AMS (KLM) & ABZ (Eastern) !! Thus I really can't see as to what your point is.
Now I would have thought, great idea to pursue "any" airline to provide services into DTV, but surely not at such a critical time to look to introducing competition on the only services that you do provide. It's commercial suicide !
Incidentally
the BMI brand which is still respected on Teesside
by whom !???
