For big airport, terrible
For big airport, who ever designed it did not think about it being user friendly. Heathrow airport in the UK is as big or bigger, and it was designed to be user friendly. Frankfurt flughafen is simply one of the worse airports I have ever been there and I have been to over 5o in my life. But then this is nothing unusual in Germany as most the NHS has n Germany are not user friendly for n any way what so ever
