United Airlines has unveiled plans for a variety of new routes and additional flights from its hubs in Chicago, Denver, New York Newark and San Francisco.

From May 2, 2020 the carrier wants to run daily flights between Newark and the French city of Nice (competing with all-business class carrier La Compagnie on the route).

United will operate the service with reconfigured Boeing 767-300ER aircraft, fitted with 46 of its Polaris business class seats.

From May 20, 2020 the carrier plans to launch flights from Newark to Palermo, Italy. Both routes are subject to government approval.

Flights to the Caribbean island of Curaçao are planned to operate on Saturdays from December 7, 2019 on a Boeing 737-700, a route also subject to approval.

A seasonal service between San Francisco and New Delhi will become year-round on December 5, 2019, operated by a B787-9 Dreamliner.

United also said it would add “additional flights” to Amsterdam, London, Frankfurt and Zurich and resume seasonal summer service to destinations including Athens, Naples, Porto and Barcelona.

Newark-Amsterdam and Newark-Frankfurt will get second daily flights from March 28, 2020, both on B767-300ERs.

Chicago O’Hare to Zurich will become a daily year-round service on March 28, 2020.

Subject to approval it will also expand service between Denver and London to year-round from November 1, 2019.
