- 56%Carrier
- 27%National Airspace System
- 14%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,572 of the 6,348 delay minutes reported here. The split is drawn from 6,348 delay minutes reported on DL 1124.

Connections and routes
What a delay on this flight costs
8.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 515 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on one other city pair in the data, including RSW to ATL (93), but none flew often enough under DL 1124 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to RSW only.
One caution: this is a thin sample. 347 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
