Phoenix Sky Harbor serves more than 120,000 passengers daily, with more than 1,200 flights per day, and has a total economic impact of more than $38 billion per year. We take pride in meeting the needs of our region’s thriving population, and planned improvements will add to our ability to remain America’s Friendliest Airport. Sky Harbor served nearly 39 million passengers in 2021. To keep pace with the Valley’s growth, Phoenix Sky Harbor Airport will need more terminal space and parking, better roads, airfield improvements, and options for moving people and airplanes around the airport more quickly. Upcoming improvements to Sky Harbor are often referred to as the Airport Development Plan.
