I would agree, I wouldn't start a flight with deboarding, either. In fact, nobody mentioned starting a flight with deboarding.
So, you admit that, if somebody load a flight at a gate, he will most probably, start a new flight and not disembark passengers This mean, it is not mandatory that these carts are present, near the aircraft in these circumstances.
Moreover, just after loading a flight at a gate, the user will simply see no GSX services at all around his aircraft, on the tarmac. He must choose first what he want to do and obviously, by doing this, he will indicate to GSX what configuration could be the best one. So, it is wrong to affirm that GSX cannot guess IN TIME, what is the best to do.
The problem is if I am finishing a flight and getting ready to start a flight, I expect deboarding to start right away. I don't expect the baggage trucks to start arriving five minutes later, which is going to delay my next flight.
With my last solution, you will simply not wait at all. Therefore, your argument is simply invalid.
I don't know why you're trying to pick a fight with me.
Because you and Umberto, you answer in a way where you try to convince me that I am wrong, moreover in an unfair manner, by ignoring scrupulously some obvious facts & truths I mention.
I personally never really notice the empty baggage trucks drive off whenever I start a flight and call for boarding because I'm usually in the flight deck getting the flight set up. By the time I go outside to look at the airplane, they're already long gone.
I personally have pleasure to switch to external camera, from time to time, especially, when boarding my passengers on airport, where I spend hours to customize my position, in order to have a spectacular PAX boarding from the terminal, on the tarmac ground and hate to see these stupid carts passing trough them !
Every tastes are in the nature !
