The number of passengers going through Phoenix Sky Harbor International Airport declined slightly during the first half of 2025 versus the same time in 2024, a rare occurrence for the airport.
Though there have been several years of only slight year-over-year passenger growth in January through June, there have only been three other instances in the past 20 years of decreased travel: 2020, during the COVID-19 pandemic, and 2008 and 2009, during the Great Recession.
Three other years in the past two decades — 2016, 2013 and 2012 — saw slight passenger increases in the first half of the year but finished the year with slight decreases from the year prior.
