Boston to Myrtle Beach

What the Data Says About BOS to MYR

The Boston to Myrtle Beach corridor (BOS → MYR) covers roughly 738 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 2,992 flights in the dataset, this route posts a 80.9% on-time rate with an average delay of 76.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,376 flights were recorded on this pairing — 32 cancelled (2.3%) and 3 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,992 total flights analyzed, the 80.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.4-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 91% on-time, while Jul 2025 came in at 66% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the BOS to MYR route, the combination of a 80.9% on-time rate, 76.4-minute average delay, 2.3% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
