Atlanta to Green Bay

What the Data Says About ATL to GRB

The Atlanta to Green Bay corridor (ATL → GRB) covers roughly 774 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 1,977 flights in the dataset, this route posts a 83.3% on-time rate with an average delay of 66.7 minutes when flights run late. Over the most recent 24 months of BTS data, 741 flights were recorded on this pairing — 4 cancelled (0.5%) and 2 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,977 total flights analyzed, the 83.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.7-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).

Monthly performance varies, so review the monthly table above to see specific periods. For travelers evaluating the ATL to GRB route, the combination of a 83.3% on-time rate, 66.7-minute average delay, 0.5% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
