United and Washington Dulles eye concourse improvements

United Airlines and the operator of Washington Dulles are looking at ways to improve some of the aging facilities at the hub airport. The two are evaluating an addition to concourse C that would benefit both arriving and departing travellers in the more 30-year-old facility. The departures level of the wing would accommodate United's new premium Polaris lounge, while the ground floor would be used to improve the flow of arriving international passengers. United, which operates about 63% of seats at the airport, confirms that it is planning an addition to concourse C to house the Polaris lounge, declining to comment further. The carrier has previously said that its Polaris lounge for international premium passengers at Dulles is scheduled to open in 2019, following a series of delays. <br/>
