Greeks are very confident of the sunny weather they enjoy all year long. In fact they are so confident, that the nation's largest air carrier, Aegean Airlines, installed a live weather broadcast in Berlin, in the middle of Sony Center and promised Germans to fly them to Greece half price, if the weather in Greece got cloudy. The billboard broadcasted live in the first week of May, streaming the weather of Athens and Paros island from dawn till sunset. The live stream gathered a lot of curious passersby who stayed and enjoyed the greek sunny view while wishing for a cloud to appear. Throughout those days, the weather in Greece did justice to the airline's promise, with a lot of sun and high temperatures that kept people waiting and waiting. Until the third day, that suddenly a cloud appeared in Paros island’s sky, instantly activating a 50% discount for Berliners, who rushed to book their flights to Greece. The live stream was also available live on Youtube in order to help the rest of German residents win holidays to Greece. Concept and implementation were delivered by Ogilvy Greece for Aegean Airlines.
