It would be helpful to display at least the IATA codes on country maps in addition to the red dots.
Yah right, i miss this too!
I think, that would be unreadable, as there would be that many airport codes on this little map… A mouse hoover function, that shows airport informaion would be better, but I guess that is very tricky to implement
Check out this tool i found in german forum.
It helps a lot!
