United Airlines took delivery of its first Boeing 777-300ER Dec 21. It is the airline’s first new aircraft to come fully installed with the recently introduced United Polaris business class seating configuration. The aircraft is scheduled to enter service Feb 16, 2017 and will be the first of 14 777-300ERs United expects to put into service in 2017. United will operate the new aircraft on its Newark Liberty-San Francisco route, flying 6X-weekly. The airline expects to begin 777-300ER intercontinental service between San Francisco and Hong Kong March 25, with the aircraft replacing a Boeing 747-400 currently being used on the route. The airline unveiled its United Polaris premium business class product Dec 1, with the opening of a newly redesigned airport lounge at Chicago O’Hare International. <br/>
