It would seem to be a huge European hub with German quality and punctuality. But no! There are a lot of inconsistencies, errors and malfunctions, everything is very long and unpredictable. It is really better to arrive at least two and a half hours in advance - you can get stuck at the checkpoint for an hour, they can stand in line for passport control for 40 minutes, only one tape can work at the inspection and everything will be the same despite the fact that the queue is already a hundred meters and 40 minutes before boarding.
