Delay causes
Why AA 2306 runs late
Late-arriving aircraft accounts for 53% of the 9,188 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 25%National Airspace System
- 22%Carrier
- 1%Extreme weather
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,188 reported delay minutes here, that single category outweighs weather by 53 to one. The split is drawn from 9,188 delay minutes reported on AA 2306.
Cancellations run at 3.60%, against 1.89% nationally. That is about one flight in 30 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
24.1% 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 1,562 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 four other city pairs in the data, including MSP to PHX (30), PHX to MSP (30) and STT to JFK (16), but none flew often enough under AA 2306 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to BOS only.
One caution: this is a thin sample. 278 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 2306
For a booking, the cancellation rate is the figure to plan around on AA 2306: 3.60% of its 278 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
