there used to be some horrendous bus stop flights in the US - out in places like Wyoming and Minnesota - you started to lose track of the number of takeoffs you'd done - NW had a few served by 727's
Still some in Australia - 4 -5 stops out from places like Cairns or Alice and then reverse the flight back in the afternoon (or go on round the circuit clockwise one day and anti-clockwise the next)
better than no flights at all but ................
