Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on DCA to ROC carries a cancellation problem, not just a delay problem: 6.5% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about two flights in three arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 820 flights, with a median arrival 3 minutes late.
The national on-time rate over the same period is 77.3%, so PSA on DCA to ROC runs 12 points behind the country as a whole. Across a thousand flights that is about 124 extra late arrivals.

Carrier by carrier
PSA against every carrier on DCA to ROC
PSA flew 820 of the 1,032 flights on DCA to ROC, most of the route. Its 64.9% on time is 3 points worse than the route as a whole, which runs 67.9%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Envoy at 89.7% to PSA at 64.9%.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Book the morning departure. Flights leaving between 8am–11am arrive on time 74.4% of the time, against 58.6% for the afternoon window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 310 flights scheduled in it.

The latest arrival of the period was on 29 April 2026, 5 hours 35 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across April, July, June and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 April 2026 | 5 hours 35 minutes | Late-arriving aircraft |
| 9 July 2026 | 5 hours 26 minutes | Extreme weather |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 57% of the 21,000 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 27%Carrier
- 10%National Airspace System
- 5%Extreme weather
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 21,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 20,703 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 74.4% on time here.
Cancellations run at 6.46%, against 1.89% nationally. That is about one flight in fifteen 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 stage length
What a delay here costs
15.7% 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.
At 296 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.
The return leg runs 63.5% on time across 820 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 820 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 PSA on DCA to ROC
Put together: the delay figures matter less here than the 6.46% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 766 completed flights over 12 months sit behind that.
