Everything is fine, no problem. There are no quibbles. The presence of documents is mandatory, as without it.
The only drawback is that there is a large crowd for departure, the European Union passes without queuing into its booths, the rest wait. Long. It is advisable to arrive 3 hours in advance, 2 hours is end-to-end
It's a good airport. For sports activities. As long as you get from one end to the other, you can definitely become an athlete. If you fly Lufthansa, then everything is fine. But other companies have enough problems. This terminal is too small. Especially for international flights
A large airport, lots of shops, cafes. But you can get lost. Fashion brands either didn't catch the eye or they don't exist. Robots are driving, selling mineral water, juices, and lemonades.
