Edinburgh isn't and won't be anytime soon a big transit hub.
Trying to extrapolate that because Edinburgh is bigger than Iceland it will become a point of transit is nonsense. That's too simplistic.
No based carriers and it's transatlantic offerings are limited and not all year round.
A huge number of visitors to Edinburgh are in the domestic figures because they arrive on BA flights etc from the London area not directly from overseas.
Anyone that's flown up from London will testify to that.
I am sure someone could produce exact figures but the busiest routes are probably still mostly domestic.
