I thought this show is very good. Sure, the passengers have some drinks here or there, and there are some sexual themes(like the women have to look their best, affairs, etc). It does show that for the 60's, woman could be strong and independent, unlike the show, The Playboy Club, which uses women as sex objects, which got a better rating than Pan Am. Really?
I think it's iffy for 13 and under, but 14+ can handle it.
