I'm traveling in business class from JNB to SFO with a connection in Zurich. I'm being given the opportunity to bid for an upgrade from JNB to ZRH. If our part of three wins the bid, would we have access to the Swiss First Class Lounge in Zurich or would be have access to the Business Class Lounge per our connecting flight? Unfortunately, bidding is not available on our connecting flight to SFO. Any insights would be appreciated.
