Frankfurt airport is marginally better. Flights stop in the middle of the runway. Take a bus. Buses are late. Walk for what feels like eternity. No regard for accessibility. I’ve met multiple senior citizens frail, waiting for their wheel chairs and worried that they’re going to miss their connecting flights.
As good as German engineering is, the airport infra is equally worse.
It’s a shame. I like flying lufthansa. They have the shortest flight times to Asia from the west coast.
