Midway Airlines' marketing is going to pot-literally. In a first for the airline industry, Midway is designating a separate bathroom for women on board its five aircraft. The women's rooms will feature an extra mirror, soap and lotion dispensers, fresh flowers, a hand-painted mural and state-of-the-art automatic sanitary toilet seat cover. The other restroom remains unisex. A radio, print and outdoor campaign from Bozell Worldwide, Chicago, supports.
