CHICAGO, ILLINOIS — United Airlines has announced that it would suspend seven long-haul routes during June because of its idled Boeing 777s powered by Pratt & Whitney PW4000.

The affected routes include New York, Newark - Kahului, Honolulu, and Tokyo Narita, and Washington Dulles - Sao Paulo Guarulhos, Geneva, Honolulu, and Dublin International.

The airline is planning to resume these routes starting from July. 

United's 19 PW4000-powered B777-200s and 33 B777-200ERs have been grounded since  February 2021 due to an uncontained engine failure on one of them. United's B777s will return to service once cleared by the US Federal Aviation Administration (FAA).

The US carrier's 22 B777-200ERs and 22 B777-300ERs powered by General Electric's GE90 engines are not affected by the grounding.
