SACRAMENTO (CBS13) – More than one million passengers flew in and out of Sacramento International Airport in May- the most in more than a decade.

1.052 million passengers officially moved through SMF last month. It was a 12.3% increase over May 2017 and the highest since July 2017.

Part of the increase is credited to airlines offering more flights. Those additional flights led to 11.8% more seats being available in May 2018 compared to May 2017. Currently, 12 airlines operate out of Sacramento International, with more than 155 daily nonstop flights offered.
