Woke up early at night to go to the airport, lounged at the good business lounge and met up with some friends.
Later took Swiss' great A330 business class flight to Zurich, only to experience a very mediocre lounge at terminal A.
After a long layover, continued to Hamburg.
Checked in the hotel and were upgraded to a lovely Park suite (finaly suite upgrade certificate as a diamond member).
Later, we walked the city to visit a couple of churches, the city hall, the lake and a shopping mall.
Lounge dinner was adequate and we went to sleep rather early, as we were so tired.
