Atlanta to Fort Lauderdale

What the Data Says About ATL to FLL

The Atlanta to Fort Lauderdale corridor (ATL → FLL) covers roughly 581 miles and is served by 31 carriers, based on Bureau of Transportation Statistics reporting. Across 42,441 flights in the dataset, this route posts a 77.2% on-time rate with an average delay of 67.1 minutes when flights run late. Over the most recent 24 months of BTS data, 14,253 flights were recorded on this pairing — 188 cancelled (1.3%) and 27 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 31 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 42,441 total flights analyzed, the 77.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.1-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 2025 posted the best performance on this corridor at 85% on-time, while Jun 2025 came in at 55% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the ATL to FLL route, the combination of a 77.2% on-time rate, 67.1-minute average delay, 1.3% recent cancellation rate, and 31 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
