March 2014 was the busiest month in the history of Phoenix Sky Harbor International Airport. More than 4 million passengers traveled through Phoenix Sky Harbor in March, 4,029,861 to be exact. That marked a 3.2 percent increase over March of 2013 and the first time the Phoenix airport has seen more than 4 million passengers in a single month.

“Spring Training, students on spring break, Arizona’s great weather and our state’s many attractions brought visitors to Phoenix in record numbers,” said Phoenix Aviation Director Danny Murphy. “Our tourism partners, such as hotels and rental car companies also enjoyed a tremendous spring travel season.”

“Valley hotels and resorts saw a 2.9 percent increase in occupancy in March 2014 compared to the previous March,” said Debbie Johnson, president and CEO of the Arizona Lodging & Tourism Association. “Tourists spend more than $19 billion every year in Arizona. An increase in the number of visitors to our state is good for everyone.”

In the first three months of this year, the Airport saw a 3.3 percent increase in passenger numbers compared to the same time period in 2013. April statistics for Sky Harbor are not yet available.
