Regional airlines fly 64% of the takeoffs and landings at Chicago's O'Hare International, 74% at Seattle-Tacoma and 52% at New York's LaGuardia Airport.
Outside of New York, three runways were opening this week at other major airports: Seattle-Tacoma International Airport, Washington Dulles International Airport and Chicago O'Hare International Airport.
Even if Seattle-Tacoma's 11 Forbes 500s companies are thrown in (Seattle is not on our list because it is not one of the ten largest metropolitan areas), New York still stays on top.
