Atlanta to Pittsburgh

What the Data Says About ATL to PIT

The Atlanta to Pittsburgh corridor (ATL → PIT) covers roughly 526 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 15,385 flights in the dataset, this route posts a 85.2% on-time rate with an average delay of 61.4 minutes when flights run late. Over the most recent 24 months of BTS data, 5,657 flights were recorded on this pairing — 65 cancelled (1.1%) and 6 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 15,385 total flights analyzed, the 85.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.4-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Nov 2024 posted the best performance on this corridor at 95% on-time, while Jul 2024 came in at 66% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the ATL to PIT route, the combination of a 85.2% on-time rate, 61.4-minute average delay, 1.1% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
