Siberia Airlines, one of the largest Russian discount carriers, is selling advertising space, and lots of it. You can put your brand on anything you want - from tickets and towels to the entire airplane. The list of brandable surfaces includes carpeting, seats, tables, in-flight magazines, flight assistants' uniforms, interior walls, shades, trays, napkins, boarding passes, schedules, luggage rafts, bathrooms, the hangar, the walls of the office building, and VIP lounges.
You can also run commercials on the in-flight TV and radio, and organize special onboard events and promotions. -- Sostav.ru (in Russian)
