Pittsburgh to Atlanta

What the Data Says About PIT to ATL

The Pittsburgh to Atlanta corridor (PIT → ATL) covers roughly 526 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 15,364 flights in the dataset, this route posts a 89.3% on-time rate with an average delay of 72.6 minutes when flights run late. Over the most recent 24 months of BTS data, 5,656 flights were recorded on this pairing — 67 cancelled (1.2%) and 16 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 15,364 total flights analyzed, the 89.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.6-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, Sep 2025 posted the best performance on this corridor at 96% on-time, while Jan 2025 came in at 73% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the PIT to ATL route, the combination of a 89.3% on-time rate, 72.6-minute average delay, 1.2% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
