Fort Lauderdale to Atlanta

What the Data Says About FLL to ATL

The Fort Lauderdale to Atlanta corridor (FLL → ATL) covers roughly 581 miles and is served by 30 carriers, based on Bureau of Transportation Statistics reporting. Across 42,458 flights in the dataset, this route posts a 77.5% on-time rate with an average delay of 74.4 minutes when flights run late. Over the most recent 24 months of BTS data, 14,251 flights were recorded on this pairing — 196 cancelled (1.4%) and 33 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 30 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 42,458 total flights analyzed, the 77.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.4-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, Sep 2025 posted the best performance on this corridor at 83% on-time, while Jul 2024 came in at 61% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the FLL to ATL route, the combination of a 77.5% on-time rate, 74.4-minute average delay, 1.4% recent cancellation rate, and 30 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
