Very fun and nice idea, but this topic is dead?
C'mon guys, let's go again. I will edit 2 different airport to this message soon. Let's start guessing again.
Edit:
1)
2)
<-- This one just don't have anything else than this one runway.
And few first clues:
-Both are in the same country, and in close range of each other
-Only one of these airports is in Euroharmony's timetable
-And one of these airports is in an island.
