Virgin America (San Francisco) has won the last eight takeoff and landing slots at Washington National which American Airlines (AA, Dallas/Fort Worth) and US Airways (Phoenix Sky Harbor) relinquished as part of their anti-trust agreement with the US Department of Justice.

Virgin said the new Reagan slots would allow it to increase service to its sole existing Washington National route to San Francisco. New flight schedules out of Washington National and New York Newark are to be published later this month.

As previously reported, Southwest Airlines (WN, Dallas Love Field) secured 54 slots at the Washington airport, allowing 27 additional daily flights. Southwest has now said it will not use an additional two slot pairings awarded it on the grounds that they could be used only on Sundays. JetBlue Airways (B6, New York JFK) won 40, including 16 it had been leasing from American. Reuters says Frontier Airlines (F9, Denver International) lost its bid for the slots.

American Airlines was also required to divest 34 slots at New York La Guardia of which Southwest was awarded 22 of those and Virgin America twelve.
