New York travelers will have to wait longer to experience one of the most significant projects in the transformation of John F. Kennedy International Airport (JFK). The highly anticipated New Terminal One is now expected to welcome its first passengers in the first quarter of 2027, moving beyond its previous target of opening sometime in 2026.
The delay affects a project that is intended to fundamentally reshape JFK’s international south side. With an estimated cost of $9.5 billion, the terminal is replacing the existing Terminal 1 as well as the former Terminals 2 and 3. When completed, it will provide 2.6 million square feet of new airport space and become the largest terminal at JFK.
For passengers, however, the immediate consequence is straightforward: the existing facilities will remain in use for several more months. Construction teams and airport partners still have work to complete, while the terminal operator is preparing complex systems, airline operations, concessions, and passenger processes before the building can safely open.
New Terminal One Opening Delayed Until Q1 2027
The latest schedule calls for the first phase of the New Terminal One to open during the first quarter of 2027. The project had previously been expected to begin operations during 2026, with earlier expectations pointing toward a summer opening.
This represents another adjustment for one of the largest individual components of the broader JFK redevelopment program. The terminal operator says the remaining work involves not simply completing construction but also ensuring that the many systems required for a modern international airport are properly tested.
That testing is particularly important because opening a major terminal involves considerably more than finishing the building itself. Passenger processing, baggage handling, security, gates, airline operations, retail areas, technology systems, and other functions must work together from the moment travelers arrive.
The first phase will include 13 gates plus one temporary gate. This configuration will allow the New Terminal One to begin serving passengers before the entire development is finished.
The operator emphasized that the additional time is intended to ensure the terminal is ready for passengers rather than simply meeting a calendar date. The goal is to have systems and operational procedures thoroughly tested before the first travelers arrive.
A 23-Gate International Gateway for JFK
The New Terminal One is designed as a substantial expansion rather than a simple replacement for JFK’s aging Terminal 1. The completed facility will contain 23 gates, including 22 widebody gates, giving international airlines significantly more infrastructure for long-haul operations.
The second phase will follow the opening of the initial facility. Once the new terminal begins operating, JFK’s existing Terminal 1 is expected to be demolished. That space will then be incorporated into the next stage of construction, which is planned to add another nine gates.
The final 2.6-million-square-foot complex will also include more than 300,000 square feet dedicated to retail, dining, and lounge facilities. The scale is intended to give international travelers a substantially different experience from the aging facilities currently serving the airport.
Sustainability is another major feature. The project includes 13,000 solar panels, which are planned to create New York City’s largest solar array. That element adds an energy-generation component to a terminal project already notable for its enormous physical footprint and financial scale.
International Airlines and New JFK Lounges
The terminal is also being developed around a broad group of international airline partners. The planned carrier lineup includes Air France, KLM, Etihad Airways, LOT Polish Airlines, EVA Air, Turkish Airlines, Air New Zealand, Air China, and Philippine Airlines, among others.
The presence of so many international airlines reflects the terminal’s intended role as a major long-haul gateway. Its large number of widebody gates will be particularly important for carriers operating services between New York and Europe, Asia, the Middle East, and other international markets.
Travelers will also have access to six planned lounges, including a major new Air France lounge. As airlines increasingly use premium lounges as an important part of the international travel experience, these facilities are expected to become a significant component of the new terminal.
JFK’s Wider Airport Redevelopment Continues
The delayed opening does not mean JFK’s modernization program has stopped. New Terminal One is one part of a much broader redevelopment involving multiple terminals across the airport.
Another major component is Terminal 6, which is being developed as a new facility expected to serve JetBlue, United Airlines, and several Star Alliance carriers. Together with other terminal expansions and renovations, these projects are intended to create a substantially different JFK airport over the coming years.
The New Terminal One is also notable for the scale of its public-private investment. The Port Authority of New York and New Jersey describes the $9.5 billion project as the largest public-private partnership in the United States. The development is expected to create approximately 10,000 jobs, including around 6,000 union construction positions.
The project’s eventual impact will therefore extend beyond passenger facilities. Its additional gates, larger international-processing capacity, commercial space, and airline infrastructure are intended to support JFK’s position as one of the world’s major aviation markets.
What Travelers Should Expect in 2027
For now, travelers using JFK will continue to encounter the airport’s existing terminal infrastructure while construction and operational preparation proceed. The crucial milestone will be the Q1 2027 opening of the first phase, rather than completion of the entire 23-gate complex.
That distinction matters because the New Terminal One will evolve in stages. The initial 13-gate facility, plus its temporary gate, is expected to begin passenger operations first. The existing Terminal 1 can then be demolished, allowing the second phase to add the remaining nine gates.
The revised schedule means the long-awaited transformation will take longer than previously expected, but the finished project is designed to deliver a dramatically larger international facility. For JFK passengers and airlines, the most important changes will ultimately come from the combination of 23 gates, 22 widebody positions, 2.6 million square feet, expanded lounges and commercial areas, and modernized passenger infrastructure.
If construction, testing, and operational preparations remain on schedule, the first travelers will finally enter the New Terminal One in early 2027, marking the next major step in JFK’s long-running redevelopment.
