As if we aren’t fed up enough with the increasingly annoying ads flashing on TV and computer screens. Next time you fly you may find yourself surrounded by equally bothersome poster ads tacked onto every inappropriate inch of your airplane.

Spirit Airlines, Ryan Air and others are raking in millions of dollars from sponsors by displaying ads. Passengers will not only see the big ads, but also little ones on tray tables, barf bags, flight attendant aprons and every other space they can think of.
