A late pushback is often recovered here: of 81 departures that left 15 minutes late or more, 25 still arrived on time. In the other direction, 19 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DFW.

Delay causes
Why AA 1177 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 5,732 reported delay minutes.
- 39%Late-arriving aircraft
- 33%Carrier
- 17%National Airspace System
- 11%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,732 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 5,732 delay minutes reported on AA 1177.
Cancellations sit at 1.93% against a national 1.89%, which is ordinary. Diversions add another 1.10%.
Connections and routes
What a delay on this flight costs
8.5% 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 a little over an hour, which a normal layover absorbs.
The 1,192 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.
AA 1177 is not only a DCA to DFW flight. It also flew DFW to DCA (302 flights, 84.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 363 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.
