Not only does Boeing give tours (more of an opportunity to look down from an observation deck at some planes being built), but they also have an surplus outlet. Never know what they'll have, but they have had first-class seats. It's in Kent, Wash.
Also, to go on the tour, get there early. They give away the tickets for the day beginning at 8 or 8:30 a.m. and often they're gone for the whole day by 11 a.m.
