Olympic Airline is the official airline of Greece and is based in Athens. The Logo of Olympic Airlines is similar to that of Olympics but instead of 5 rings, it has six rings. The actual logo of the airline was a white eagle, which was similar to a propeller and had five rings and the name Olympic. Which was later changed to only six colored rings. The first five rings denote the five continents whereas the sixth ring stands for Greece as the airline belongs to Greece.
