Busy gate
Hi.
Let's say I have two aircraft using the same gate at an airport and only one of those has a schedule route. When the aircraft that has an assigned route arrives at the gate it finds that the door is occupied with the other aircraft that does not have an assigned route and loses the turn to make the programmed route. The aircraft that obstructs the door should not be a reason to stop all the day the other one. It should be charged extra fee and allow it to fly normally.
Regards
