Philadelphia International Airport (PHL) July 2025 Operational Report

Flight Activity Overview

Total Departing Flights: 13,265

Year-over-Year Change in Departing Flights: −7.17%

In July 2025, Philadelphia International Airport handled 13,265 departures, a year-over-year change of −7.17% as airlines fine-tuned summer schedules and rebalanced capacity across the Northeast. The adjustment modestly reduced frequencies on select regional routes while keeping core domestic flows intact, limiting broader network impact for the region.

On-Time Performance and Cancellations

Departure On-Time Performance: 58.38%

Year-over-Year Change in OTP: −6.15%

Cancelled Flights: 432

Year-over-Year Change in Cancellations: 2.37%

Departure OTP averaged 58.38%, pressured by recurrent afternoon thunderstorms in the Mid‑Atlantic and ATC flow programs; cancellations reached 432 for the month. Knock‑on delays and longer taxi‑out times affected connections, while carriers increased day‑of‑ops re‑accommodation and tightened turn processes to contain disruptions.

Airlines Serving PHL

American Airlines (AA) maintains the largest presence at PHL, supported by a mix of U.S. legacy and low‑cost carriers and seasonal transatlantic operators. The hub structure prioritizes domestic connectivity across the Northeast, Midwest, and South, with summer long‑haul links complementing the network.

Outlook

Over the next 4–8 weeks, schedules at Philadelphia International Airport should remain broadly stable with departure OTP near current levels; late‑day convection and weekend peaks are the main risk windows. Passengers should prefer morning departures, allow 60–90 minutes of buffer for security and connections on busy days, and monitor real‑time gate and weather alerts via the airport or airline app.
