The JFK T1 Airtrain station will close (again) from 1 May 2023 for at least 7 months due to construction of the new T1.
Shuttle buses from Terminal 4 to Terminal 1 will run daily from 9 a.m. to 11 p.m., while buses from Terminal 8 to Terminal 1 will be available 24/7.
Road construction and traffic changes at T1 will also occur leading to potential traffic.
