The world’s Top 20 airlines by seats and frequencies

    Seats and departing frequencies are key factors in determining the “size” of an airline, and while not the only indicator both clearly represent just how large a carrier can be. American Airlines sits at the top of the lists of available seats and departing frequencies with over 4.75 million seats and 43,000 departing frequencies per week.

    The big four US airlines dominate the top of the lists, making up almost 20% of the global market share.
