What French film is being referred to in the Will & Grace pilot?

In the pilot episode of Will %26amp; Grace, at the very end after Grace runs out of her wedding, Will describes a French film that they had seen in college. In the film, a man and a woman who are destined for to be together keep missing each other and then finally meet on a plane. Is this a real film? And, if so, what is it called and where can I find it?|||Hi! I've searched some info about it and I didn't find anything, so I'm assuming that it is not a real film. The only information about a reference in that episode is about John Wayne. Sorry!
