Frankfurt Airport

You're wrong. Frankfurt Hahn Airport has very little air traffic. You confused it with Frankfurt Airport which is 10 kilometers from the city of Frankfurt. This airport was a military base. Ryanair does not operate from Frankfurt Hahn, but Lufthansa has its main base there. You put the airport Frankfurt, not Hahn ;))

A lot of people are there but everything is very systematic. McDonald's sitting area gives the best view of runway... Coffee and planes arrival makes it easy to spend your layover period.

There are a lot of food for less than 5€. It’s easy to find your correspondence
