The number of people guessing it right was amazingly low. But at least the number of second tries was much higher than usual. Once again, this was an advertisement published in a local Atlanta publication in late 1980, following the inauguration of Hartsfield Atlanta International Airport Click or tap on the ad to reveal the answer.
How to guess it?
First of all, remember one thing: this ad was on a local Atlanta publication and the wording makes it seem as if Atlanta was a DESTINATION, not a hub. After all, the airline already flies to "New York, Chicago, Houston and Los Angeles." And its "(...nationality...) touch" comes in April 1981. A hub wouldn't use that kind of sentence.What else? It's all in the 747, and in its basic colour scheme. And furthermore, the very small blank wouldn't justify a very long airline name. So, a three-letter name would make more sense.
