Tallahassee to Miami

What the Data Says About TLH to MIA

The Tallahassee to Miami corridor (TLH → MIA) covers roughly 402 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 6,016 flights in the dataset, this route posts a 82.4% on-time rate with an average delay of 67.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,535 flights were recorded on this pairing — 46 cancelled (1.8%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,016 total flights analyzed, the 82.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.6-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, Apr 2025 posted the best performance on this corridor at 92% on-time, while Mar 2024 came in at 66% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the TLH to MIA route, the combination of a 82.4% on-time rate, 67.6-minute average delay, 1.8% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
