The 2.6 million-square- foot New Terminal One will be a best-in-class international terminal and serve as the anchor terminal in the Port Authority of New York and New Jersey’s $19 billion transformation of JFK. It is being built on sites now occupied by Terminal 1 and the former Terminal 2 and Terminal 3, where it will anchor the airport’s south side.

The first phase, including the new arrivals and departures halls and first set of 14 gates, is slated to open next year. Completion is expected for 2030, when the New Terminal One will have a total of 23 gates and more than 300,000 square feet of retail, dining and lounge space. It will be the largest terminal at JFK, the largest standalone international terminal in the nation and nearly the same size as the two new terminals at New York’s LaGuardia Airport combined.

Airlines that will be located at the New Terminal One include Air France, KLM, LOT Polish Airlines, Turkish Airlines, Etihad, Korean Air, Air New Zealand, Air China, Gulf Air, Qatar Airways and EGYPTAIR.

In addition to the New Terminal One, the JFK plan calls for a second new terminal, modernization and expansion of two existing terminals, new ground transportation center and new, simplified roadway network. A rooftop solar microgrid will be installed to enable operations to continue in case of any power disruptions and to reduce carbon emissions.

The New Terminal One is privately funded by a consortium of labor, operating and financial partners, including Ferrovial, JLC Infrastructure, Ullico and Carlyle. It is being constructed by a design-build team led by AECOM Tishman and Gensler. Unibail-Rodamco-Westfield is the concessions developer and manager, including dining, retail and duty-free concepts.

In July, the New Terminal One closed a nearly $1.4 billion green bond issuance with proceeds being used to fund the remainder of the first-phase construction. In June 2024, the New Terminal One developers secured a record-breaking $2.5 billion green bond for the project. It was the largest municipal bond financing to date for an airport project and was increased from an initial $1.5 billion due to high investor demand.

JLL’s duties outlined

The firm’s Aviation group, which is part of JLL’s Industrials division, will maintain HVAC, plumbing, electrical, fire life safety and other essential technical services at the terminal. A key component of the work will include operational readiness and transition and start-up support beginning early next year to ensure smooth activation and ongoing terminal efficiency. JLL will also manage and operate the building management and electric power monitoring systems and switchgear that will power charging stations for the all-electric ground support equipment fleet, aligning with evolving trends in commercial real estate focused on technology and decarbonization.

Marisa Von Wieding, vice president of operations at New Terminal One, cited JLL’s expertise and ability to manage and maintain the critical infrastructure that will be powering the next-generation terminal. Von Wieding said in prepared remarks the partnership will be setting new global aviation standards for operational excellence, technological integration and sustainability.

JLL Aviation Managing Director Koley MacKay said in a prepared statement the group’s specialized aviation expertise positions it to uniquely support New Terminal One’s vision, including managing cutting-edge sustainable systems and providing seamless integration of complex building technologies.

The firm’s Industrials division provides strategic real estate advisory to aviation authorities, airlines, cargo operators and airport-related enterprises. In addition to facilities management, the specialized aviation team offers strategic portfolio planning, transaction services, project management and operational optimization.

In September, the Aviation group was tapped by WestJet, Canada’s leading low-cost airline and second-largest carrier, to provide facilities management across a 1.9 million-square-foot portfolio. The airline’s corporate headquarters in Calgary and 17 airport locations nationwide are included in the portfolio.
