My wife and I have a 10 hour layover in Frankfurt. Are there showers airside open to the public (i.e. not in a lounge accessible to specific frequent flyers) and is there comfortable seating in the public areas? Or do we have to pay for lounge access at non-exclusive lounges like the Sky Lounge? Any info would be greatly appreciated. And does anyone have any info on the Sky Lounge at FRA? I have not really been able to find any info on it.
