Thought, so. Too bad...
Yes, I could do that, but it is very slow, as I'd have to create 1 route, clear schedule of the aircraft, add the route, and then repeat for other routes. ANd since my plane now has 3x7 flights, I would have to do this 21 times for each aircraft
Oh, by the way, will I need more staff if I have 21 flights opposed to 3 even if they do exactly the same flights?
