Well, the airline Air Europa often decorates their planes. Years ago, when I went to Paris I flew with this company and the plane was decorated with images of Minnie and Mickey to advertise Disneyland Paris. The plane astonished me because I was only ten years old! However, they only decorated that plane in order to advertise the theme park I mentioned before.
To be honest, if they wanted to advertise Disneyland Paris I think that they did their best, since Mickey and Minnie are the dominant figures of this theme park. I can’t think of an alternative to it.
