Other mistake: In the scene where Frank is watching the Bond film: turn on subtitles. You will notice that when Bond says "Tell me Jill, why does he do it?", the subtitles read "Tell me Joan, why does he do it?". (00:57:05)
Other mistake: One of the end credits is "saxaphone solo." It should be "saxophone."





Answer: It lasts several months. The stewardesses were juniors and seniors from the University of Arizona, whom he fake-recruited for a PR project for Pan-Am (they were not supposed to be real stewardesses, but dress like them and be photographed in various European capitols). Frank was frequently being asked where his "crew" was, so he thought it would lend him credibility.
This is inaccurate. When he leaves Brenda, he calls the university immediately and says that he will be stopping by the next morning, and we see that they return to Miami International Airport. So, it was definitely not the University of Arizona. And I don't recall anyone asking Frank where his crew was; the question he got was what kind of equipment he was on. As far as the ladies are concerned, he likely left them right there in Miami. Much easier to keep a low profile on his own.
