what is the main airport in washington dc
Washington Dulles International Airport Dulles is one of the three major airports in the larger Baltimore–Washington metropolitan area with more than 21 million passengers a year.[5][6] Dulles has the most international passenger traffic of any airport in the Mid-Atlantic outside of the New York metropolitan area, including approximately 90% of the international passenger traffic in the Baltimore-Washington region.[7] On a typical day, more than 60,000 passengers pass through Washington Dulles to and from more than 125 destinations around the world.[5][8] However, Dulles Airport now ranks behind both Baltimore-Washington International Airport (BWI) and Ronald Reagan Washington National Airport (DCA) in total annual passenger boardings.[9]
Airports of London Located in the London Borough of Hillingdon, Heathrowmap1 is by far the largest of London's airports and considered the main gateway into the United Kingdom for non-European visitors. Heathrow has four terminals and two parallel runways. Due to the location in London's western suburbs, Heathrow has had trouble trying to expand, with various expansion projects being cancelled.[9]) As a result, the airport consistently runs at over 99% capacity and is often included on lists of the worst-rated airports in the world.[10] However, on 1 July 2015 Heathrow's expansion plan was suggested as the best option by the Airport Commission and on 25 October 2016 a new northwest runway and terminal was approved by the Government.
