| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 December 2025 | 11 hours | Carrier |
| 9 August 2026 | 2 hours 30 minutes | Late-arriving aircraft |

Delay causes
Why AA 1179 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 4,575 reported delay minutes.
- 40%Late-arriving aircraft
- 40%Carrier
- 16%National Airspace System
- 5%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,575 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 4,575 delay minutes reported on AA 1179.
Cancellations run at 2.82%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
9.5% 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.
At 1,726 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on two other city pairs in the data, including PHX to RNO (1) and RNO to PHX (1), but none flew often enough under AA 1179 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to SNA only.
One caution: this is a thin sample. 284 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 AA 1179
For a booking, the cancellation rate is the figure to plan around on AA 1179: 2.82% of its 284 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
