The Economist has an interesting short piece and infographic on international airlines and the price you pay versus the service you receive. They used customer satisfaction data from Skytrax and lined that up against flight-volume data from FlightStats.com.

At the bottom of the satisfaction list? United and American Airlines.

Another interesting tidbit was the “worst airports to sleep in” category. Port Harcourt International Airport in Nigeria topped that list… And that isn’t a good thing.
