A couple people already mentioned this, but San Francisco International
Airport does have exhibits.  Right now there is an interesting one
called "Shaken not Stirred: Cocktail Shakers and Design."  I have been
fairly impressed by the exhibits I have had a chance to see (when I am
not running through the terminal to catch a flight!!).  The airport
museum's website is located at www.sfoarts.org.  I suggest taking a
look if you have time.
