Orlando to St. Louis

What the Data Says About MCO to STL

The Orlando to St. Louis corridor (MCO → STL) covers roughly 882 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 13,444 flights in the dataset, this route posts a 77.8% on-time rate with an average delay of 66.9 minutes when flights run late. Over the most recent 24 months of BTS data, 4,831 flights were recorded on this pairing — 61 cancelled (1.3%) and 16 diverted (0.3%). 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 13,444 total flights analyzed, the 77.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.9-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 Mar 2024 came in at 63% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the MCO to STL route, the combination of a 77.8% on-time rate, 66.9-minute average delay, 1.3% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
