They had reschedule the flight by 2 hours earlier. So we had to be earlier at the airport, the weather is changing.
The thing is, the persons who do the immigrations, are also do the emigrations. So everybody had to be through the emigrations, before the plane arrives. That means, we had to be at the airport 5 hours before the flight, since they did only tell, when the check-in process starts, but not, when it's closed. So all the shuttle bring the people on the start of the check-in.
