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 color scheme. And furthermore, the very small blank wouldn't justify a very long airline name. So, a three-letter name would make more sense.
