Saw this movie on overnight network TV (probably CBS) back in late 70s/early 80s. A group of people travel to Paris by plane and when they finally get there they separate and are individually frustrated because they can't meet who they were expecting or get anything else done. They occasionally catch up with each other and complain about these problems. At the end of the movie two of them discover that actually the plane had crashed and they're all dead. The individual stories had a sort of disembodied quality which in retrospect really fit.
Shades of "The Sixth Sense" but maybe 20 years earlier.
Always wanted to see it again.
