| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 October 2025 | 17 hours 20 minutes | Carrier |
| 8 May 2026 | 8 hours 12 minutes | Late-arriving aircraft |

Delay causes
Why AA 2840 runs late
Late-arriving aircraft accounts for 52% of the 9,615 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 35%Carrier
- 12%National Airspace System
- 1%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,615 reported delay minutes here, that single category outweighs weather by 52 to one. The split is drawn from 9,615 delay minutes reported on AA 2840.
Cancellations run at 4.51%, against 1.89% nationally. That is roughly one flight in twenty 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
16.4% 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 678 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 PHL to ORD (76), but none flew often enough under AA 2840 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to PHL only.
One caution: this is a thin sample. 288 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 2840
For a booking, the cancellation rate is the figure to plan around on AA 2840: 4.51% of its 288 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
