Phoenix Sky Harbor International Airport had a record-breaking start to spring: March 2019 saw more than 4.5 million passengers traveling through "America's Friendliest Airport."

The traffic broke last year's record by 3.3 percent. 

“These numbers show the continued demand for travel to and from our state,” said Phoenix Mayor Kate Gallego. “It’s crucial with the increased passenger demand that we continue to provide world-class facilities and service to our customers. The capital investment program currently underway at Sky Harbor would allow us to accommodate much-needed future capacity.”

On average, each day about 120,000 people travel through Sky Harbor, but in March, that number was around 146,000.

The airport is currently undergoing several projects to enhance the facilities and prepare for more growth.
