A $9.5 Billion Terminal Just Missed Another Deadline

The operator of JFK’s New Terminal One has confirmed the building will not open to passengers in 2026 as planned, and now expects to begin handling flights in the first quarter of 2027. The stated reason is time: additional weeks are needed to finish construction, run systems testing and complete operational rehearsals before the first passenger walks through. A spokesperson framed it as a decision not to open until everything had been properly tested, which is the correct instinct and also what every delayed terminal says.

The project is the largest of its kind at any American airport. At roughly $9.5 billion, New Terminal One replaces the existing Terminal 1 along with the sites of the demolished Terminals 2 and 3, consolidating them into a single international gateway several times the size of what stood there. Phase one, the part opening in early 2027, delivers 13 permanent gates plus one temporary gate, enough to begin moving airlines across while the rest of the complex is still being built.

That sequencing is why the delay compounds. The existing Terminal 1 cannot be demolished until its airlines have moved into the new building, and phase two, which adds a further nine gates, cannot start until the demolition does. A slip at the front of that chain pushes everything behind it. For the carriers that have committed to the terminal, including several international airlines currently squeezed into ageing facilities, it means another year in buildings that were supposed to be gone.

Passengers flying international out of New York should plan around the old layout for all of 2026 and into 2027. Air France has already announced it will operate one of the largest lounges at the new terminal when it opens, an indication of how much premium capacity is waiting on the building. Anyone booking a connection through JFK next summer should assume today’s terminal geography, today’s inter-terminal transfer times and today’s minimum connection windows still apply.
