See the airlines using JFK’s New Terminal One, what the project replaces, its opening phases, and how to confirm the right terminal for your flight.
JFK’s New Terminal One is the phased international replacement for existing Terminal 1, built across its site and the former Terminals 2 and 3 footprint. More than a dozen publicly named airline partners—including Air France, KLM, Korean Air and Etihad—are expected to use it; the full announced roster appears below.
Within our Aviation & Real-World Flying coverage, the crucial distinction is that this is an airport redevelopment, not a new airport or merely a renamed gate area. Its airport remains John F. Kennedy International, identified in aviation as KJFK.
What exactly is JFK’s New Terminal One?
The project is a complete replacement for the existing Terminal 1 on JFK’s south side. The finished terminal is planned to have 23 gates, most able to accommodate wide-body aircraft, along with new departure, arrival, baggage and border-processing facilities.
“New Terminal One” is the project name. Once flights transfer, passenger documents may simply identify the facility as Terminal 1, so travellers should not expect “NTO” to appear as a separate terminal number.
Which airlines will use the New Terminal One?
The published partner roster has named the following 15 international airlines, although they will not necessarily move on the same date:
- European and transatlantic carriers: Air France, Air Serbia, KLM, LOT Polish Airlines, Neos, SAS and Turkish Airlines.
- Asia-Pacific carriers: Air China, Air New Zealand, China Airlines, EVA Air, Korean Air and Philippine Airlines.
- Middle Eastern and African carriers: Etihad Airways and Royal Air Maroc.
Air China and China Airlines are separate carriers despite their similar names. The first is based in mainland China; the second is based in Taiwan.
This is a list of publicly announced airline partners, not an immutable gate allocation. Additional airlines can join, operating agreements can change, and some carriers may transfer in a later phase rather than on the first day.
When will the New Terminal One open?
The terminal is being delivered in stages so JFK can continue handling international flights during construction. The published programme called for an initial 2026 phase with the main departure and arrival halls and 14 gates, followed by the remaining gates and full completion around 2030.
The existing Terminal 1 remains part of the transition sequence: the first new section is built alongside it, airlines transfer, and the old building is then removed to make room for later construction. That is why an airline can be committed to the New Terminal One while still appearing at the old Terminal 1 beforehand.
How do I confirm which JFK terminal my flight uses?
Use the terminal shown for the operating airline on your booking or boarding pass, then recheck it before travelling. Do not choose a drop-off point solely from the development’s airline list.
Codeshares cause many wrong-terminal mistakes. An Air France flight number operated by Delta follows Delta’s terminal assignment, for example; our guide to Delta’s JFK terminal and connection arrangements covers that case.
Gate numbers are even less permanent than terminal assignments. They may change on the day because New Terminal One uses common-use facilities and must accommodate aircraft with very different wingspans and handling requirements.
How is the New Terminal One represented in flight simulators?
A simulator’s version of KJFK may show the old Terminal 1, an active construction site or part of the finished development, depending on the scenery’s source date. Default airport data and third-party scenery do not update simply because a real airline changes terminals.
For operational taxiways, runway details and charted construction changes, use our KJFK airport diagram and instrument-chart collection. Airport diagrams identify movement areas, not airline tenants, so they should be used alongside the airline assignment rather than as a terminal directory.
Microsoft Flight Simulator 2024 users can also review our coverage of enhanced JFK scenery and its modelled airport features. Before planning a gate arrival, check whether the scenery represents the old terminal, an interim construction stage or the completed layout.
