As we try to strive for realistic timings, a couple of suggestions...
1, Passenger times, when we ask for boarding, instead of a generic time, maybe a box allowing us to enter how many passengers we have actually loaded, so we would have to think about when is a good time to load passengers etc,
2, Same with fuel and food.
I know we are not all going to sit and wait 2 hrs to load an aircraft, as we can adjust the timings for passengers etc, why not enable us to enter a certain amount where we have to think about timings for departures etc, so we can meet our departures timings
