Hi,
I'm evaluating an international connection (potentially in next May) via ZRH from MAD to HKG by SwissAir (LX) in a single air ticket - the arrival flight is supposed to land at 22:00 while the departure to HKG is at 22:40.
While the connection is paired by LX online, how feasible is it to connect in less than 40 min via skymetro and passport/security controls before the departure gate in terminal E closes ?
While LX online has paired other connections via FRA by LH with more appropriate connection time, I prefer to avoid both.

I have not committed to any air ticket yet.
Thank you in advance.
