These figures cover 325 flights between September 2025 and August 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 April 2026 | 5 hours 4 minutes | Late-arriving aircraft |
| 14 February 2026 | 4 hours 23 minutes | Late-arriving aircraft |
| 19 June 2026 | 3 hours 20 minutes | Extreme weather |

Delay causes
Why AA 1584 runs late
Late-arriving aircraft accounts for 42% of the 3,042 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Late-arriving aircraft
- 36%Carrier
- 14%Extreme weather
- 7%National Airspace System
Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 3,042 delay minutes reported on AA 1584.
Cancellations sit at 0.92% against a national 1.89%, which is ordinary. Diversions add another 0.31%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.7% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 1584 is not only a DFW to LAS flight. It also flew LAS to DFW (283 flights, 85.7% 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. 325 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.
