Is the SkyLounge accessible for Delta One passengers whose final destination is FRA given that the lounge is airside? Not overly-familiar with the FRA layout and Schengen vs. non-Schengen zones always confuse me.
Looks like there are showers operated by the airport as a backup, but even for those it's not entirely clear to me from the confusing airport website/map that those are landside.
