Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1947, check with American Airlines.
AA 1947 earns a D, which is as low as this site's scale goes for a reason. Only 56.7% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average an hour and a half. Treat any tight connection here as a coin flip. That rests on 351 flights, with a median arrival 3 minutes late.
The national on-time rate over the same period is 77.6%, so AA 1947 runs 21 points behind the country as a whole. Across a thousand flights that is about 209 extra late arrivals.

These figures cover 351 flights between July 2025 and June 2026. Beyond the headline rate, 20.8% 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 1947 flies
AA 1947 flies DCA to SAT without a single fixed slot. Its most common scheduled departure was 19:59, used on 122 of 351 flights, with 17:30 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 19:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 1947 runs 12 points worse at 56.7%. 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 1947 quarter by quarter
AA 1947 did not run the same all year. Its best quarter was Oct–Dec 2025 at 74.7% on time and its weakest Jul–Sep 2025 at 42.5%, a swing of 32 points on roughly 88 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202583 flights74.7%
- Jan–Mar 202685 flights57.3%

By weekday, AA 1947 did best on Monday at 66.7% on time and worst on Sunday at 43.8%. Each day rests on about 50 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 1947 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 59% of the 13,000 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.
- 59%Late-arriving aircraft
- 23%Carrier
- 14%National Airspace System
- 3%Extreme weather
59% 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 13,000 reported delay minutes here, that single category outweighs weather by 19 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 12,540 delay minutes reported on AA 1947.
Cancellations sit at 2.28% against a national 1.81%, which is ordinary. Diversions add another 0.28%.
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. 20.8% 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 1,380 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 two other city pairs in the data, including PDX to MIA (1) and PDX to CLT (1), but none flew often enough under AA 1947 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to SAT only.
One caution: this is a thin sample. 351 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 1947
For a booking, AA 1947 is a flight to put a long connection behind. 20.8% 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.
