Sorry for having to ask but I tried to search but after a few minutes couldn't find anything.
I am flying Business NRT-ZRH-LHR on LX and will have 2:45 at ZRH. I know from my past transfer at ZRH that only the A wing has the Biz/Sen lounge with showers. I assume the flight to LHR isn't in the Schengen (A) zone given my past intra-EU flights to LHR, right? With that much time on one ticket and bags through I imagine there is enough time to clear immigration into A for the lounger/showers and then make it back to the LHR flight?
