I was just recently at Amsterdam Airport Schiphol and noticed ING “Here, I come campaign” that brilliantly plays on it ads placements at the airport.
As you wonder around the airport, look outside from your plane and at any loading area ING have huge large format signs saying “Paris, here I come”, “Milan, here I come”, “Retail therapy here I come”…
Before you place an ad, especially outside advertisements think about who will see it and how you can connect the ad directly to them.. ING have done this brilliantly.
