Cheap Flights from Philadelphia to Atlanta — $48

Philadelphia International Airport (PHL) is the region’s primary international gateway and a major network hub, seeing a mix of legacy carriers and low-cost airlines on domestic and transatlantic routes. The airport sits about 7 miles southwest of Center City, with SEPTA regional rail taking roughly 25–30 minutes to 30th Street Station and fares typically in the low single digits; taxis or rideshares can take 15–30 minutes depending on traffic and cost more. Ground transport also includes shuttle services and on-site parking for drivers. Pros: frequent nonstop connections and consolidated terminals for easier transfers; cons: can be busy during peak hours and security lines may be longer at times.

Hartsfield–Jackson Atlanta International (ATL) is a major international hub and one of the busiest airports in the United States, typically serving a mix of full-service carriers and a strong presence from Delta and several domestic operators. It’s located about 10–13 miles south of downtown Atlanta, with MARTA rail providing a direct connection in roughly 20–25 minutes for a modest fare, while ride-hailing and taxis usually take 20–40 minutes depending on traffic and cost more. The airport’s two parallel terminals and extensive amenities can make connections convenient but walking distances and busy security lines may be tiring. ATL can be competitive on fares for both domestic and international routes, though peak times and last-minute bookings often raise prices.
