Atlanta to New York

What the Data Says About ATL to LGA

The Atlanta to New York corridor (ATL → LGA) covers roughly 762 miles and is served by 35 carriers, based on Bureau of Transportation Statistics reporting. Across 42,079 flights in the dataset, this route posts a 80.8% on-time rate with an average delay of 71.6 minutes when flights run late. Over the most recent 24 months of BTS data, 15,857 flights were recorded on this pairing — 274 cancelled (1.7%) and 75 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 35 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 42,079 total flights analyzed, the 80.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 71.6-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, Feb 2024 posted the best performance on this corridor at 89% on-time, while Jun 2025 came in at 62% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the ATL to LGA route, the combination of a 80.8% on-time rate, 71.6-minute average delay, 1.7% recent cancellation rate, and 35 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
