I look at the ads in the inflght magazine and Sky Mall catalog trying to find something that interests me. But I ingored the ad on the tray table. So how does this one extra ad generate more revenue that the magazine and catalog? There isn't much reason to pull down the tray table when there's no food, and if there is food the tray table is covered up by the tray (duh!) so you can't see the ad. I don't get it. The ad should be on the food tray.
