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 2026 at 42.4%, 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.

By weekday, AA 1947 did best on Saturday at 68.8% on time and worst on Sunday at 44.9%. Each day rests on about 50 flights, so a gap of 24 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AA 1947 runs when it is late
AA 1947 often beats the schedule: 97 of 343 completed flights, 28%, arrived 15 minutes or more early. The 144 late arrivals split 39 under half an hour, 37 between 30 and 60 minutes, and 68 an hour or more.

Share of 343 completed flights by arrival against schedule.
24 of 137 late departures made up the time and arrived on time, 18% of them. In the other direction, 31 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SAT.

Delay causes
Why AA 1947 runs late
Late-arriving aircraft accounts for 55% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 26%Carrier
- 16%National Airspace System
- 3%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 17 to one. The split is drawn from 12,642 delay minutes reported on AA 1947.
Cancellations sit at 1.71% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
Connections and routes
What a delay on this flight costs
19.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
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. 350 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. 19.8% 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.
