Fly with American Airlines from Chicago to Philadelphia

Find great value on US Airways flights from CHI to PHL when you book with CheapOair! Locals call it Philly; it was the original capital of the nation and is a city with an impressive past. Philadelphia has its charm lying in its historic sites and culture. If this is a family trip, take your kids to the Philadelphia Zoo, this is an animal packed zoo covering an area of 42 acre and offering great opportunities to interact with the animals housed here. The Liberty Bell is a dramatic and powerful bell; the Liberty Bell Center is a not-to-be-missed attraction in Philadelphia. At the end of the Benjamin Franklin Parkway is the Philadelphia Museum of Art covering an area of 10 acres and housing more than 300,000 artworks. The Center City west is home to many notable museums including Mutter Museum, African American Museum and the Academy of Natural Sciences.
