For a decade a I filled out complaint forms every week at United Red Carpet Clubs explaining that they were being short-sighted charging for internet service, a service they could provision for a few hundred dollars a month and would have drawn customers to them. They finally got around to fixing their stupid contract about the time airports started giving away wifi for free in the concourse, making the lounge the tier 2 place to be for a business traveler.
Finally, Frankfurt has realized the same thing. Oddly, Munich has been giving away access cards for years now, but Frankfurt was always a dead zone for an international traveler. today I was very pleased to see this slightly oddly worded greeting.
