Today’s Washington Post story on the Flight Attendants wage concession vote and an impending American Airlines bankruptcy makes the following statement in order to be relevant to the local community:

Although [American] is the world’s largest airline, it is one of the smallest in the Washington area. The airline accounts for 9 percent of the flights at Reagan National Airport, 3 percent at Dulles International and 8.7 percent at Baltimore-Washington International. US Airways, Delta Air Lines and Southwest Airlines are the region’s most dominant major carriers. (Emphasis mine)

The dominant carrier at Washington-Dulles airport is, of course, United Airlines.
