Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on DCA to HSV carries a cancellation problem, not just a delay problem: 4.7% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 935 flights, with a median arrival 6 minutes early.
The national on-time rate over the same period is 77.3%, so PSA on DCA to HSV runs 8 points behind the country as a whole. Across a thousand flights that is about 79 extra late arrivals.

Departure window
When PSA runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 36 points, against half a point between the best and worst carrier.
- 5am–8am—
- 8am–11am226 flights81.7%
- 11am–2pm288 flights70.1%
- 2pm–5pm162 flights61.5%
- 5pm–8pm48 flights45.5%
- 8pm–5am211 flights66.3%
Scale runs 35% to 85%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 45.5% on time, against 81.7% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 288 flights scheduled in it.
Across the year
PSA on DCA to HSV through the year
December is the weak month at 56.2% on time, against 84.9% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 112 flights.
Across the week, Monday is the strongest day at 74.8% on time and Wednesday the weakest at 62.6%, a spread of 12 points.

The worst days
Worst days for PSA on DCA to HSV
The latest arrival of the period was on 5 April 2026, 11 hours 2 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 April 2026 | 11 hours 2 minutes | Carrier |
| 23 March 2026 | 6 hours 43 minutes | Carrier |
| 18 January 2026 | 5 hours 20 minutes | Carrier |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 58% of the 22,000 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 24%Carrier
- 11%National Airspace System
- 6%Extreme weather
- 0%Security
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 22,000 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 21,746 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 81.7% on time here.
Cancellations run at 4.71%, against 1.89% 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 stage length
What a delay here costs
12.6% 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 613 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 return leg runs 69.6% on time across 937 flights, within half 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. 935 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 HSV
Put together: the delay figures matter less here than the 4.71% 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. 889 completed flights over 12 months sit behind that.
