America’s top 20 airports grew by 2.5% in 2011; Miami fastest-growing as Houston Bush drops from 7th to 10th

Officials cut the ribbon on a new route launch

Miami International Airport grew the fastest out of the top 20 airports in the US last year, +7.3%, and the airport has already this year seen the arrival of another new airline – LAN Colombia – suggesting that the end to the growth has not yet been seen.

This week, anna.aero has collected 2011 traffic data for the top 20 airports in the USA, which reveals that between them passenger numbers grew by an estimated 2.5% in 2011. Of the top 20 airports, only two (Chicago O’Hare and Houston Bush) failed to record year-on-year growth, while only Miami recorded passenger growth of more than 6%. In terms of ranking, Houston Bush has dropped from seventh to tenth, as a result of which Las Vegas, San Francisco and Phoenix have all moved up a place. Further down, Seattle-Tacoma has overtaken Detroit for 16th place.
