BOULDER, Colo.

— An airport in the United States is hiring nearly three times as many people as it did in July and August, and the agency overseeing the jobs is looking to boost its workforce by as much as 15 percent to meet a new state requirement for hiring an additional 2,400 full-time workers.

Airport officials said Tuesday that the airport in downtown Boulder is hiring 2,200 full- and part-time employees as of early June, a 15 percent increase from the same time last year.

They said the job growth is being driven by a surge in demand for flights.

The Boulder International Airport Authority said it’s the largest airport hiring increase in recent years and has more than tripled the number of jobs it has employed in the past two years.

Boulder International Airport is one of two major airports in Colorado that require a minimum of two full- or part-timers to work in the airport’s airport operations center.

The authority said it currently employs more than 1,400 employees and has a capacity of more than 50,000 passengers.

The airport has been hiring in-person workers and by appointment since August and has seen a recent surge in hiring of temporary workers and people who are seeking temporary jobs.

The authority said its in-flight training and pilot program, which allows passengers to fly in and out of the airport and take advantage of its amenities, has been a huge hit, with more than 3,000 flights booked last month and nearly 1,000 scheduled flights this month.

Bryan C. Fishell, president and CEO of the Boulder Airport Authority, said the authority has had to increase staffing levels at the airport to meet the new state requirements, which were announced in March and require the agency to hire at least one additional full-timer and one part-timer for each full-timer and part, a total of three full-times, per year.

Fishell said it was also the busiest time of the year for in-airport job openings, and he expects the authority to add another 5,000 to 7,000 employees as it continues to hire in-office workers.

Boulder is one other major airport with a requirement that employers hire one full- time employee for every full-tandem or part time worker.

Frishell said that as part of its plan to hire full-tset employees, Boulder has hired two full timers to fill in for people who leave the airport for vacation or other reasons.

He said the number will grow as more full-testers and part timers are added to the staff.
