US Airways is launching service to 11 new destinations and adding flights to three existing destinations at Washington Reagan National Airport following the closing of its slot transaction agreement with Delta Air Lines on December 13.

Eight of the 11 new communities that the airline will serve currently have no service to Washington’s downtown airport, according to US Airways. The new flights, which begin on March 25, are the next step in US Airways’ plan to focus on its core service areas of Washington D.C., Philadelphia, Phoenix and Charlotte.

“We are excited to expand our service to customers traveling to and from our nation’s capital as well as increase jobs at Washington National Airport,” said Doug Parker, US Airways’ chairman and CEO. “When our expansion is completed, US Airways will offer more than 230 daily flights and directly support more than 1,500 aviation jobs at Washington National.”

US Airways operates large hubs at Philadelphia, Charlotte and Phoenix and is the largest carrier at Washington D.C.'s near-downtown Reagan National Airport

The final phase of the airline’s plan to focus on its core service areas starts on July 11 and will add more new routes from Washington. The airline will announce the routes in February.

To support the expanded service, US Airways will add more gates at Washington Reagan National Airport, build a second US Airways Club (located near its new departure gates) and will hire approximately 125 airport customer-service and fleet-service employees.

In the first phase of its expansion at Washington National, US Airways will add new daily service on March 25 to Birmingham, Alabama; Fayetteville, North Carolina; Islip, New York; Little Rock, Arkansas; and the Florida cities of Jacksonville, Pensacola, Tallahassee and Fort Walton Beach. These destinations currently have no existing service from Reagan National, according to US Airways.

US Airways will also add new service to Memphis, Tennessee; Omaha, Nebraska; and Ottawa in Ontario. These communities are currently served by other carriers at Reagan National.

The airline will increase its service to Bangor, Maine and Savannah in Georgia to daily flights. US Airways currently serves the two destinations from Reagan National only on weekends. US Airways will also add a further daily nonstop frequency to Hartford, Connecticut.

At New York’s LaGuardia Airport, US Airways will reduce its schedule from current service levels. It will remain the third-largest carrier at the airport, offering customers 65 daily weekday flights. The airline will continue to operate its hourly dual-class Shuttle service to Washington and Boston, and high-frequency service to its Charlotte and Philadelphia hubs.

US Airways will also continue to serve Pittsburgh and its Phoenix hub from LaGuardia. All US Airways flights will continue to arrive and depart from Terminal C, where the airline will build a new, 3,500-square-foot US Airways Club, to be completed this spring.

According to the airline, once both phases of the transition are complete, 99 per cent of US Airways’ available seat miles (ASMs) will operate to or from its core service areas or on US Airways Shuttle services.

This represents a 16-percentage-point change from 2006, when, following the merger of US Airways and America West Airlines, only 83 per cent of the airline’s ASMs touched its core focus areas or were US Airways Shuttle flights.
