When I first arrived in Geneva, one of our clients was Baboo airlines. About a month into the job, their holding company forced them to consolidate agencies and vendors, and the account was sent to Saatchi & Saatchi, here in town.
These are a couple of the current billboards. I rather like them.
I think they do exactly what EasyJet's ads do. But in a different way. They're clearly branded - you know from across the street you're looking at a Baboo ad even before you read it. And they're a simple, interesting way of saying, "Fly to [fill in the blank] for cheap."
