Historical statistics for July 2025 to June 2026, not live status. For today’s AA 499, check with American Airlines.
AA 499 draws a D−. Roughly one flight in two arrives at least 15 minutes late, and the typical late arrival is close to two hours behind schedule. Build slack into anything you connect to. That rests on 298 flights, with a median arrival 5 minutes late.
The national on-time rate over the same period is 77.6%, so AA 499 runs 18 points behind the country as a whole. Across a thousand flights that is about 182 extra late arrivals.

These figures cover 298 flights between July 2025 and June 2026. Beyond the headline rate, 23.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When AA 499 flies
AA 499 flies DFW to SAT without a single fixed slot. Its most common scheduled departure was 17:34, used on 59 of 298 flights, with 18:30 (44 flights) and 17:30 (38 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 17:34 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 499 runs 9 points worse at 59.4%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AA 499 quarter by quarter
Quarter by quarter AA 499 held fairly steady: 59.4% in Jul–Sep 2025, 61.6% in Oct–Dec 2025, 55.8% in Jan–Mar 2026 and 59.3% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202568 flights59.4%
- Oct–Dec 202588 flights61.6%
- Jan–Mar 202653 flights55.8%
- Apr–Jun 202689 flights59.3%
Scale runs 45% to 65%. Rows with fewer than 30 flights show a dash.
By weekday, AA 499 did best on Tuesday at 67.4% on time and worst on Sunday at 40.0%. Each day rests on about 43 flights, so a gap of 27 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 499 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 12,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

- 37%Carrier
- 7%National Airspace System
- 2%Extreme weather
- 0%Security
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 12,000 reported delay minutes here, that single category outweighs weather by 23 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 11,714 delay minutes reported on AA 499.
Cancellations run at 5.03%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 23.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The same number turns up on three other city pairs in the data, including SAT to DFW (82), DFW to OKC (2) and OKC to DFW (2), but none flew often enough under AA 499 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to SAT only.
One caution: this is a thin sample. 298 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 499
For a booking, the cancellation rate is the figure to plan around on AA 499: 5.03% of its 298 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
