| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 December 2025 | 6 hours 35 minutes | Late-arriving aircraft |

Delay causes
Why DL 1130 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,185 reported delay minutes.
- 39%Late-arriving aircraft
- 34%Carrier
- 21%National Airspace System
- 6%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,185 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 5,185 delay minutes reported on DL 1130.
Cancellations are rare at 0.63%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
10.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 692 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 three other city pairs in the data, including BOS to AUS (19), SJC to SLC (14) and SLC to SJC (14), but none flew often enough under DL 1130 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MCI only.
One caution: this is a thin sample. 316 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.
What to do with this
Booking DL 1130
For a booking, read DL 1130 as 78.0% on time with 0.63% cancelled over 316 flights. Those are rates from the past twelve months, not a forecast for any particular day.
