Airport Geographical Names

A German court has ruled that the airline Ryanair cannot use the word "Duesseldorf" for an airport 42 miles (70 km) from that city. According to the comments posted on the BBC article, the practice of naming a distant airport for a major city is quite common. Does this mean that BWI will have to change its name from Baltimore/Washington International Airport since its 33 miles (53 km) from D.C.? Tell us what you think!
