A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AA 852 runs level with that at 84.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why AA 852 runs late
Carrier accounts for 69% of the 7,218 delay minutes carriers reported here, and the remaining four split what is left.
- 69%Carrier
- 25%Late-arriving aircraft
- 5%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,966 of the 7,218 delay minutes reported here. The split is drawn from 7,218 delay minutes reported on AA 852.
Cancellations run at 3.12%, 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
8.1% 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 3.1 hours, which a normal layover absorbs.
The 641 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 DCA (29), DFW to LAS (2) and DCA to BOS (1), but none flew often enough under AA 852 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to DFW only.
One caution: this is a thin sample. 256 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 852
For a booking, the cancellation rate is the figure to plan around on AA 852: 3.12% of its 256 scheduled flights did not operate. A late arrival costs about 3.1 hours, but a cancellation costs the day, so leave a later option open.
