United is restoring Boeing 777-300ER service to Newark. The airline’s largest aircraft type will return to its Northeast hub next year with regularly-scheduled flights.
According to Ishrion Aviation on Twitter/X, the aircraft is set to be deployed on routes to Dubai, Frankfurt, and Rome. Currently, the jet is primarily used from United’s San Francisco and Washington Dulles hubs.
The carrier last operated scheduled 777-300ER flights from Newark in October 2023, per Cirium Diio schedule data.

Starting on March 29, 2025, the aircraft will operate flights to Dubai and Frankfurt. Later, on May 22, it will be added to the Newark-Rome route.
These routes were previously slated to be operated by a mix of 777-200 and 787-10 aircraft.
United’s 777-300ERs are configured with 350 seats, including 60 in Polaris business class and 266 in economy. Currently, the airline has 22 777-300ERs in its fleet.
