Mousing over 3-letter airport codes and 2-letter airline codes usually reveals the name.
However some people post the 3 letter code for obscure airports around the world which do not show up, which is frustrating because they might not the name of the city they are talking about. It's also a good idea to only use the 3-letter codes and not the 4-letter codes for airports since the mousing over feature only works for 3-letter codes.
(sorry for the gripe)
If you have never designed an airplane part before, let the real designers do the work!
