The second "game" (maybe I should stop calling this a contest: the only prize is your own pride of knowing the answer!) was much easier than the previous one. Everybody had the correct answer, according to the e-mail messages I got! This ad was taken from the back cover of a
National Geographic issue of the 1970s, United States version.

How to guess it?
This one was extremely easy to guess. There were actually three clues. First thing is that it is a Boeing 747 operator. This should already eliminate many airlines. Secondly, the cabin crew had the bright red uniforms... We're getting closer! Finally, look at the routes flown by this airline. Many fly by Minneapolis/St. Paul. And today, that airline still uses Minneapolis as a major hub.
