Dallas Love Field was the fastest-growing U.S. airport by percentage between 2007 and 2017, while traffic at Memphis Airport shrunk the most, according to an analysis by UpgradedPoints

UpgradedPoints based the analysis on FAA statistics charting the number of passengers emplaned annually at individual airports. The ranking only considered airports with at least 3 million departing passengers annually.

Love Field saw its count of departing passengers increase 48% over that decade, driven by the end of the federal Wright Amendment in 2014, which had prohibited operations of all but short-haul flights from the airport. After the repeal, Love Field's dominant carrier, Southwest Airlines, amped up operations there. 

Rounding out the top three on the growth list are Austin-Bergstrom, which has benefitted from the booming growth of the Texas capital, and New Orleans' Louis Armstrong, which UpgradedPoints noted has seen a return of flights it lost after Hurricane Katrina in 2005. There also has been an influx of low-cost service in New Orleans as well as new international service. Between 2007 and 2017, enplanements in Austin grew by 39% while New Orleans enjoyed 37% growth in terms of departing passengers. 

Rounding out the top ten fastest-growing airports were San Francisco, Houston Hobby, Seattle, Fort Lauderdale, Nashville, Los Angeles and Boston. 

Memphis had the steepest passenger decline (62%) from 2007 to 2017. The airport suffered from Delta's decision to shut down its hub there. Cincinnati, another victim of Delta hub consolidation, experienced a passenger decline of 51%, the second-steepest drop. Southern California's Ontario Airport saw a decline of 35% as airlines concentrated more operations in the larger airports of that region, including Los Angeles International. 

UpgradedPoints noted that Cincinnati in particular has turned the tide in recent years. Between 2016 and 2017, the airport had a 16% increase in enplanements because Southwest entered the market and as low-cost Frontier and Allegiant grew operations there.

Rounding out the top 10 declining U.S. airports between 2007 and 2017 were Albuquerque, Cleveland, San Juan, Jacksonville, Pittsburgh, Palm Beach and Oakland.

Albuquerque was hurt by the repeal of the Wright Amendment. The airport was an essential stop for West Coast destinations from Dallas Love Field when the Wright Amendment was in effect, but the transfer in Albuquerque is no longer necessary.
