How to guess it?
The clues for this ad were not very numerous. The major one is the indicators on top of the flight information board: English and German. However, most people were mislead by those and immediately thought of a German airline. But remember: there are other German-speaking countries in Europe: Switzerland and Austria are large enough to have their own airline and are in Central Europe. Switzerland's Swissair is eliminated because it flew to West Berlin (Tegel) and not East Berlin (Schönefeld). But this airline did.Remember: do NOT always consider the destinations appearing too obviously on the advertisement. They are cities to which the airline flies OUT of its original hub, most of the time.
