IB's coach is old style, I mean no AVOD or personal screen so take same reading for return flight...
An advice ZRH is served from T4S building which is the same where you arrive so don't follow the crowd after passport control and go to RSU gates in the same building with their own Xray inspection...so very easy and quick connection. If you are emerald or sapphire go to the lounge take a shower and relax...there are some beds to recover a little bit....
