I do loadsheets for BA and no, Im not in Thailand. But we can not make only LS, we have to make everything for loading. That means loading instructions too. To make this we need cargo information and booked pax to plan ULDs. When this is done and aircraft is loaded we can not just make it simple. All uld numbers, pax, seating, fuel, aircraft weight, pantry, crew and without system it takes ages to get all this info. And you do not even know if station is able to provide this info. And now imagine you are supposed to this paperwork for flight each 10 minutes. Just all the phone calls will take the time. To make manual LS is possible in theory, not in real traffic. It would be possible but you would have to break all the rules. And my colleague got into trouble because he sent LS without 9 bags on A380. We can not miss a single kilogram.
