Airbound Bay seniors know all about the intriguing, ever changing exhibits at SFO. Few, however, have a clue that there is an actual museum located in the International Terminal, designed as a replica of a 1930’s passenger lobby.They have a vast collection and library. Their current show includes models and photos of the romantic China Clipper seaplane. Hours are Sunday to Friday from 10 to 4:30. Free. It’s a great place to cool down the next time you have a flight that’s maddeningly delayed.
