Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on CLT to IAD carries a cancellation problem, not just a delay problem: 3.2% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 967 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 454 at 86.6% on time.
Set against the rest of the country, PSA's CLT to IAD record is 4 points better than the US average of 77.3%. That gap is worth roughly 42 fewer late arrivals for every thousand flights.

These figures cover 967 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
PSA against every carrier on CLT to IAD
PSA flew 967 of the 1,992 flights on CLT to IAD, about 49% of it. Its 81.5% on time is 2 points better than the route as a whole, which runs 79.5%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from United at 97.1% to American at 68.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 86.6% of the time; American Airlines manages 68.7%. Sample sizes sit next to every figure, because a two-point gap across 537 flights means less than a ten-point one.

The spread between Republic and American is 18 points, wide enough that it should decide the booking. On a hundred trips that is 18 more arrivals inside the on-time window.

Departure window
When PSA runs best on this route

- 8am–11am156 flights90.0%
- 11am–2pm305 flights84.5%

Scale runs 45% to 95%.
The 8pm–5am window is where this operation falls apart: 53.1% on time, against 91.0% for the 5am–8am 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 305 flights scheduled in it.
Across the year
PSA on CLT to IAD through the year
December is the weak month at 58.9% on time, against 92.9% in June. 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. September was the busiest month here, with 115 flights.
Across the week, Wednesday is the strongest day at 87.5% on time and Sunday the weakest at 74.6%, a spread of 13 points.

The worst days
Worst days for PSA on CLT to IAD
The latest arrival of the period was on 11 July 2026, 14 hours 6 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 11 July 2026 | 14 hours 6 minutes | Late-arriving aircraft |
| 14 August 2026 | 3 hours 42 minutes | Late-arriving aircraft |
| 21 August 2026 | 3 hours 30 minutes | Extreme weather |
| 2 July 2026 | 3 hours 20 minutes | Late-arriving aircraft |
| 4 January 2026 | 3 hours 6 minutes | Late-arriving aircraft |
Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 52% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 33%Carrier
- 9%National Airspace System
- 7%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 10,720 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.0% on time here.
Cancellations run at 3.21%, against 1.89% nationally. That is about one flight in 30 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
6.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 322 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 5am–8am window matters as much as it does.
The return leg runs 83.8% on time across 967 flights, within 2 points 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. 967 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 CLT to IAD
Put together: the delay figures matter less here than the 3.21% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 935 completed flights over 12 months sit behind that.
