Hi,
have a single air ticket issued by SwissAir to fly CX from HKG (Hong Kong) to VCE (Venice) with 90 min to connect in ZRH onto LX (SwissAir). Would my checked-in luggage be tagged all the way to VCE OR need I check it again in ZRH at the SwissAir counter on the land side ?
If latter would 90 min be enough and to what extent my onward flight is protected should CX arrives late in ZRH ?

Called CX service desk but they were unable to confirm claiming only the CX checkin counter could do so.

Thank you in advance.
