Philadelphia International Airport (PHL) screened about 13.5 million departing passengers at TSA checkpoints in the 12 months to September 30, 2026, roughly flat (-0.2%) on the prior 12 months. Over the same period, US Customs and Border Protection processed about 1.7 million arriving international passengers there. That ranks PHL 19th of 458 US airports by departing passengers screened in Passenger Index's data.
In September 2026, 1,101,779 departing passengers were screened at TSA checkpoints at Philadelphia International Airport (PHL), according to Passenger Index's compilation of TSA FOIA throughput data. CBP processed 152,778 arriving international passengers there that month.
In the 12 months to September 30, 2026, departing passengers screened at PHL were roughly flat (-0.2%) year over year; CBP international arrivals were +3.0%. Year-over-year compares the same 365 days a year earlier, using only days reported in both years.
PHL is a large hub in Passenger Index's FAA-style classification: it handled 1.5% of national TSA checkpoint throughput in the 12 months to September 30, 2026 (at least 1% is the large hub band). The FAA's official hub classes use calendar-year enplanements, so they can differ slightly.
US Customs and Border Protection processed about 1.7 million arriving international passengers (US citizens and visitors) at PHL in the 12 months to September 30, 2026. Travelers who cleared US immigration abroad at a preclearance airport (for example in Canada, Ireland or the Caribbean) arrive as domestic passengers and are not in this count.
Not from this data. TSA screening does not record where a passenger is flying, and CBP counts international arrivals only, so there is no international-departures figure to subtract. The two series measure opposite directions and are shown side by side, never added.
Airports usually report enplaned plus deplaned passengers, counting every arriving and departing passenger including connections. TSA counts departing passengers once, at screening; arrivals and connecting passengers who stay airside are not screened again, so this measure runs well below airport-reported totals, especially at connecting hubs.
TSA checkpoint throughput by airport from the TSA FOIA reading room and passengers processed from CBP Airport Wait Times, both US federal public-domain data, compiled and validated by Passenger Index. The 12-month headline is rounded to three significant figures; the monthly and annual tables are exact. Passenger Index Premium has the full daily series.
