Grand Rapids to St. Petersburg

What the Data Says About GRR to PIE

The Grand Rapids to St. Petersburg corridor (GRR → PIE) covers roughly 1,044 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,176 flights in the dataset, this route posts a 73.5% on-time rate with an average delay of 75.3 minutes when flights run late. Over the most recent 24 months of BTS data, 860 flights were recorded on this pairing — 17 cancelled (2.0%) and 3 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,176 total flights analyzed, the 73.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.3-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).

Monthly performance varies, so review the monthly table above to see specific periods. For travelers evaluating the GRR to PIE route, the combination of a 73.5% on-time rate, 75.3-minute average delay, 2.0% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
