NEW YORK — The Port Authority’s commissioners will be asked to approve part of a new five-pronged strategy to attract more air service to New York Stewart International Airport when they meet Thursday.

Huntley Lawrence, the Port Authority’s aviation director, is scheduled to discuss the strategy in presenting a resolution that recommends hiring a new company to operate, maintain and manage concessions at Stewart, according to the preliminary agenda for the meeting.

“This is a fresh start for Stewart,’’ said Patty Clark, chief strategy officer for Lawrence’s air services development team. “We’re going to do everything in a very strategic way, and we’re bringing in bigger guns to help us.”

The new company, Future Stewart Partners, is a joint venture of AvPorts, which currently operates and maintains Stewart, and Groupe ADP, which operates the three Paris, France, airports and more than 20 others.

The 10-year agreement would supplant AvPorts’ contract when it expires in October as well as Hudson News’ concessions contract when it expires in June. Its extensive terms include the expectation that the company will leverage Groupe ADP’s “networks and partnerships to market Stewart aggressively around the world” in collaboration with the Port Authority.

The resolution also indicates that Lawrence will return to the board in the coming months to recommend hiring a marketing firm for the first time to boost Stewart’s profile at home and abroad and updating the airport’s incentive program for new carriers and new routes.

The other two parts of the strategy include enlisting Hudson Valley businesses and attractions in joint efforts to drive traffic through Stewart and building on the Port Authority’s role with Hudson Valley Tourism and similar local and state agencies.

In reacting to Norwegian Air’s surprise announcement in August that it would discontinue operations at Stewart, the Port Authority hinted that it had been putting together a new plan to grow the airport that would use the low-cost carrier’s successful run as a marketing tool.

“Norwegian’s experience has demonstrated that with the right equipment, market positioning and route map, Stewart has strong appeal,” the agency said.

It added that the aviation division was in “on-going discussions with nearly a dozen airlines, both new entrants and those looking to expand service in the region” but offered no other details.
