I'm going to be passing through ZRH in the next few weeks with an ~8 hour layover -- I'd like to see the city. I'm flying in on LX C, and am a UA 1K. Do any of the lounges have ticketed (i.e., secure) baggage check so that I can leave my (heavy) laptop bag behind for the day? I've been to CX lounge in HKG that does this, but haven't had the experience anywhere else. Barring one of the lounges, does anybody know if there are lockers at ZRH where I could leave a bag for the day?
