The airline currently flies out of both Newark and JFK Terminal 4.
LOT will begin operating its JFK services out of Terminal 1 from September and will then move its Newark operations across to JFK from October 29.
The move will allow LOT to operate a greater number of flights out of JFK and to provide a more “consistent and attractive schedule” for business passengers, the airline said.
LOT recently announced a new partnership with JetBlue at JFK and the move will give passengers flying with the airline access to connecting flights to more than 80 cities within the United States.
The carrier said its own analysis showed that JFK had greater traffic potential than Newark and would better support its network strategy.
LOT will launch its Boeing 787 Dreamliner aircraft on the JFK–Warsaw route in January 2013.
CEO of LOT Polish Airlines, Marcin Pirog, said: “We believe that the consolidation of our flights from New York, and terminal changes at JFK will provide better service to our existing and future passengers, particularly in light of our new partnership with JetBlue.”
Passengers already booked on suspended Newark services will be offered a departure from JFK or a full refund.
LOT flies to more 50 cities in Europe and Northern America and has been a member of the Star Alliance since 2003.
Star Alliance members handle more than 20,800 flights per day to 1,300 airports in 189 countries.
