If the growth rate being experienced by Lambert-St. Louis International Airport continues through the end of the year, it will see one million more passengers than it did in 2015, the airport said Thursday.

Last year Lambert saw 12.7 million passengers.

For the month of September, the airport served 1.2 million passengers, up 10 percent over last year, according to airport numbers.

Through the third quarter of 2016, Lambert recorded 10.4 million passengers, a 9.1 percent increase over the same period of 2015. The third quarter year-to-year passenger growth has been 8.6 percent, the airport said.

“We’re really seeing a strong and steady travel trend hold from summer through the fall and that is very encouraging for us, and our airlines,” airport Director Rhonda Hamm-Niebruegge said in a statement. “This is a result of airlines adding new destinations, adding additional flights to current markets and upgrading to larger aircraft to meet the demand we have now in St. Louis.”
