There are problems with flying in Germany. The war in Iran is the reason. Fuel is very expensive now. Fuel is the gas for planes. It costs twice as much as before.
The airports in Germany are worried. They expect many cancelled flights in summer. 20 million people might be affected. Cheap airlines will cancel many flights. Some holiday places will be harder to reach.
Flying becomes expensive for the people. Some flight routes might disappear. The airports want help from the government. They want to pay fewer taxes for tickets. The government does not see a supply problem yet.
