Currently starting a trip in the US that connects in FRA to non-Schengen. I arrive in FRA well before 1400 local so I'm hoping the transfer bus is available for me. Beats re-clearing security or going through passport control twice to avoid it.

I'll edit this post once I get through the Frankfurt maze. Seems like it's very easy to just go find Z11, hop on a bus, get off at B50-something and find either the Maple Leaf or LH Senator lounge. I have a 2h15m connection time so should be able to use the bus and use the lounge (or maybe two lounges).

Thanks,
