Washington to New York

What the Data Says About DCA to LGA

The Washington to New York corridor (DCA → LGA) covers roughly 214 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 28,869 flights in the dataset, this route posts a 80% on-time rate with an average delay of 79.4 minutes when flights run late. Over the most recent 24 months of BTS data, 8,972 flights were recorded on this pairing — 348 cancelled (3.9%) and 8 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 28,869 total flights analyzed, the 80% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.4-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, Sep 2024 posted the best performance on this corridor at 90% on-time, while Dec 2025 came in at 58% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the DCA to LGA route, the combination of a 80% on-time rate, 79.4-minute average delay, 3.9% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
