Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1584, check with American Airlines.

AA 1584 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 325 flights, with a median arrival 8 minutes early.

Set against the rest of the country, AA 1584's record is 6 points better than the US average of 77.6%. That gap is worth roughly 62 fewer late arrivals for every thousand flights.

These figures cover 325 flights between July 2025 and June 2026. The median arrival is 8 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.

Schedule

When AA 1584 flies

AA 1584 flies DFW to LAS without a single fixed slot. Its most common scheduled departure was 08:52, used on 65 of 325 flights, with 08:30 (60 flights) and 08:54 (39 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:52 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AA 1584 runs level with that at 83.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AA 1584 quarter by quarter

Quarter by quarter AA 1584 held fairly steady: 83.1% in Jul–Sep 2025, 81.5% in Oct–Dec 2025, 86.8% in Jan–Mar 2026 and 85.1% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202591 flights83.1%
Oct–Dec 202592 flights81.5%
Jan–Mar 202653 flights86.8%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, AA 1584 ranged from 78.3% on Tuesday to 87.2% on Friday. With about 46 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AA 1584 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 3,400 reported delay minutes.

Late-arriving aircraft
41%
Carrier
37%
Extreme weather
12%
National Airspace System
10%

Extreme weather accounts for 12% 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 2.0 times the usual weather exposure. The split is drawn from 3,400 delay minutes reported on AA 1584.

Cancellations sit at 0.92% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

Connections and routes

What a delay on this flight costs

5.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on one other city pair in the data, including LAS to DFW (222), but none flew often enough under AA 1584 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. 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.

What to do with this

Booking AA 1584

For a booking, read AA 1584 as 83.8% on time with 0.92% cancelled over 325 flights. Those are rates from the past twelve months, not a forecast for any particular day.
