in Boston SWISS business-class-passengers are now welcome at the UA RCC (which also has a first-class 'séparée).

in Zurich SWISS offers (in terminal A = the Swiss main terminal: a first, a business-class, and an elegant cigar-smoker Bar-club.

Also, on the luggage level of term A in ZRH, there is the Allegra Lounge for arriving guests providing showers, breakfasts and business quipment. I believe that the Allegra lounge is free for first and business-class guests from SWISS long-haule flights, but any one can enter paying a one-time/one-entry-fee (not sure, SFr 35?).

I have also 'heard' of a fabulous personalized 'arrivals service by Rudi' - when are you here?
