Philadelphia International Airport is the largest airport in Pennsylvania and an international hub for US Airways. It’s also the main gateway to Philadelphia and Pennsylvania generally.

Philadelphia itself, affectionately known as Philly, is often referred to as “the Birthplace of America”. With a rich and varied history, it’s the fifth-largest city in the US, and has a metropolitan area spanning 12 counties. As a result the atmosphere, architecture and demographic varies quite widely depending on which area you travel to, from up-market art and design centres and historic quarters to working-class areas and quiet, leafy suburbs.

The airport is one of the busiest in the world. It has seven terminals, two of which are international terminals, and more than 160 shops and eateries. The immigration counters are notorious for being understaffed and poorly organised and long queues are common, so if you’re catching a connecting flight, make sure you arrive well in advance.
