The fastest growing North American hub airport (defined as having over 20 million departing seats) is Fort Lauderdale, which grew 11 percent between May 2017 and April 2018, according to the North America’s Fastest Growing Airports 2018 report released by OAG, the flight information company. The airport’s growth was driven primarily by low-cost carriers, with JetBlue, Southwest and Spirit Airlines operating two thirds of capacity. Newark was second fastest growing with 8 percent growth. Coming in third was Orlando International Airport, which increased capacity by 7 percent. John Grant, senior analyst of OAG, said low-cost carriers are driving exceptional demand and are the biggest contributors to airport growth in the market. The fastest growing midsized airports (3 million to 20 million seats) are Cincinnati/Northern Kentucky International; Austin-Bergstrom International Airport; and San Jose and Burbank, tying for third.
