Icy cold winters and extremely humid summers make spring and autumn the best time to take flights to Philadelphia. If you can handle the crowds, Philadelphia goes wild every 4th of July (Independence Day) with fireworks and city-wide celebrations.
A quick and easy way to get around the city centre is the Phlash, Philadelphia’s gas-engine trolley. It’s a convenient way to get to Independence Visitor Centre, Penn’s Landing and the Philadelphia Museum of Art. The trolley runs every day and can be boarded every 12 minutes at very affordable rates. It also provides direct connections to rail lines.
The main airport for travellers taking flights to Philadelphia is Philadelphia International Airport (PHL). There is a shuttle available from the airport and transfer time is about 30 minutes. Car rental companies operate at the airport as well as limousine service.
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.
