his has been discussed and answered so many times already that there are few customers including myself who prefers to keep loaders beside the plane after unloaded. It was original. I did not pay to have it changed.
Well, thats one of the bigges misconceptions that people have when buying software: You don't buy the software and you don't own the software. You just buy the right to use it. But only the programmer / developer has the right to decide what will go in or out of it and how it should work. Some very famous brands have gone down, because they decided wrong and lost the customers. You can't make all customers happy all the time, still, there is no right to claim thing's. I am sure, if it will be possible in any way, they will add the option to leave the cars there, but the first mail would be a complaint that the stair run through the loaders while arriving.
Just relax and be happy with a great product, imagine how dull an airport would be without any cars or catering or tankers... I am more than happy with what i have at the moment.
