The operator of Washington Dulles airport and American Airlines are discussing new flights, even as the carrier prepares to expand at nearby Ronald Reagan Washington National airport. Officials for the Metropolitan Washington Airports Authority and the carrier have discussed resuming flights to Miami from Dulles, and adding flights to Chicago O'Hare from the DC-area airport, said MWAA vice-president of airline business development Yil Surehan at a board meeting on 12 December. "They see an opportunity for future growth at Washington Dulles," he said of American. The airline will end its twice daily Miami-Dulles route on 19 December as part of a larger cull of underperforming markets. United will launch the route the same day. American has focused growth at its Charlotte and Dallas/Fort Worth hubs since mid-year, saying those airports are the most profitable in its system. It has cut unprofitable routes from its Chicago, Miami and New York John F Kennedy hubs in part to fund growth at Charlotte and Dallas/Fort Worth.<br/>
