We are traveling May 2 from Denver to Edinburgh (both non-Schengen) on Lufthansa transfering planes in Frankfurt. The flight to Frankfurt appears to arrive at either C or Z gates and the flight to Edinburgh (also Lufthansa) appears to leave from B gates. We have only a one hour layover in Frankfurt. What's the best/fastest way to get from C to B or from Z to B and will we have to go through pasport control and/or security? Thanks for any help you can offer.
