Philadelphia International Airport (IATA: PHL, ICAO: KPHL, FAA LID: PHL) is an airport in Philadelphia, Pennsylvania, and is the largest airport
in the Delaware Valley region. It is the 10th busiest airport in the world in terms of aircraft activity. The airport is the primary international
hub of US Airways and has service to destinations in the United States, Canada, the Caribbean, Latin America, Europe, and China.
PHL's fastest growing airline, Southwest, has been working with the city and the airport to expand and improve its facilities. Southwest recently built a
joint ticket counter lobby for the D and E terminals, one large security check point for the two terminals, and additional concessions. A hammerhead expansion
to the E concourse was finished in February 2010.
The Philadelphia metropolitan area is the fourth largest in the U.S. by the current official definition, with some
5.8 million people.
Philadelphia is one of the oldest and most historically significant cities in the United States. During part of the
18th century, the city was the second capital and most populous city of the United States, and the second largest
English speaking city in the world after London. At that time, it eclipsed Boston and New York City in political and
social importance, with Benjamin Franklin playing an extraordinary role in Philadelphia's rise.
