| 29 November 2025 | 4 hours 31 minutes | Carrier |
| 6 January 2026 | 3 hours 59 minutes | Carrier |
| 9 February 2026 | 3 hours 7 minutes | Late-arriving aircraft |

Delay causes
Why AA 777 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 5,480 reported delay minutes.
- 41%Late-arriving aircraft
- 41%Carrier
- 11%National Airspace System
- 7%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,480 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 5,480 delay minutes reported on AA 777.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
8.7% 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 an hour, which a normal layover absorbs.
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.
AA 777 is not only a DFW to LAS flight. It also flew LAS to DFW (362 flights, 70.1% 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. 365 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.
