Phoenix Sky Harbor International Airport recorded its busiest month ever in March.
More than 4.3 million passengers used the airport during the month, the latest for which data is available. That figure broke Sky Harbor's previous record -- set in March 2015 -- by 65,000.
March is usually the airport's busiest month. The region’s mild weather draws winter-weary visitors from the north and from Canada while sports fans flock to Arizona for the beginning of baseball's spring training and other sporting events.
“The increase in passenger numbers cannot only be attributed to spring break, spring training, NASCAR and other popular spring events in the greater Phoenix area, but also to an improving economy,” Phoenix Mayor Greg Stanton says in a statement announcing the passenger record.
Phoenix Sky Harbor is a hub for American Airlines and has a sizable presence from Southwest Airlines. More than a dozen additional carriers also serve the airport.
