Detroit to Atlanta

What the Data Says About DTW to ATL

The Detroit to Atlanta corridor (DTW → ATL) covers roughly 594 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 27,904 flights in the dataset, this route posts a 84.6% on-time rate with an average delay of 72.2 minutes when flights run late. Over the most recent 24 months of BTS data, 9,895 flights were recorded on this pairing — 86 cancelled (0.9%) and 19 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 27,904 total flights analyzed, the 84.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.2-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 2024 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 67% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the DTW to ATL route, the combination of a 84.6% on-time rate, 72.2-minute average delay, 0.9% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
