Just 10 percent of travelers work while on the plane, according to a survey conducted by Chicago-based GO Airport Express. Reading for fun tops the list of activities at 32 percent. Fourteen percent sleep, and 12 percent read business books and publications. An additional 7 percent watch in-flight movies and 2 percent play computer games, engage other passengers in conversations or do nothing at all.
