World’s Busiest Routes

(via Today in the Sky…)

I will give you three guesses as to what the world’s busiest route is (by number of frequencies per week).  Ok ready?  Guess.


-No, that’s not it either.

-Not even close.

Turns out that Barcelona – Madrid has the most frequent flights, with 971 (yes, 971) per week.  Rio to Sao Paulo is close with 894. 

I’ll give you 3 guesses for the most frequent in the US.


– There?  Are you kidding?

– You have no clue.

You likely didn’t guess Honolulu to Kahalui (Maui) with 639 per week. 

The article is kinda fun (if you consider this type of thing to be fun)
