Delay causes
Why AA 1797 runs late
Late-arriving aircraft accounts for 49% of the 8,967 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 24%Carrier
- 21%National Airspace System
- 6%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,967 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 8,967 delay minutes reported on AA 1797.
Cancellations sit at 1.88% against a national 1.89%, which is ordinary. Diversions add another 0.31%.
Connections and routes
What a delay on this flight costs
16.9% 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 1,055 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 MIA to PHL (9), but none flew often enough under AA 1797 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to LAS only.
One caution: this is a thin sample. 320 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 1797
For a booking, AA 1797 is a flight to put a long connection behind. 16.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
