Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on IAD to CLT 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, more than 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, American Airlines, flew 536 at 83.0% on time.
Set against the rest of the country, PSA's IAD to CLT record is 7 points better than the US average of 77.3%. That gap is worth roughly 65 fewer late arrivals for every thousand flights.

Every carrier on IAD to CLT, 1,990 flights
These figures cover 967 flights between September 2025 and August 2026. The median arrival is 14 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 IAD to CLT
PSA flew 967 of the 1,990 flights on IAD to CLT, about 49% of it. Its 83.8% on time is about level with the route as a whole at 83.1%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from United at 85.7% to Republic at 81.3%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 2 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

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 17 points, against 2 points between the best and worst carrier.
- 5am–8am54 flights86.8%
- 8am–11am267 flights89.7%
- 11am–2pm267 flights85.0%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 89.7% of the time, against 72.3% for the evening window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 267 flights scheduled in it.
Across the year
PSA on IAD to CLT through the year
December is the weak month at 69.7% on time, against 93.9% 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. September was the busiest month here, with 115 flights.
Across the week, Tuesday is the strongest day at 87.6% on time and Sunday the weakest at 74.8%, a spread of 13 points.

The worst days
Worst days for PSA on IAD to CLT
The latest arrival of the period was on 6 May 2026, 25 hours 4 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 May 2026 | 25 hours 4 minutes | Late-arriving aircraft |
| 6 April 2026 | 20 hours 49 minutes | Carrier |
| 18 June 2026 | 19 hours 28 minutes | Carrier |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 45% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 39%Carrier
- 11%National Airspace System
- 4%Extreme weather
- 0%Security
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 17,238 reported delay minutes.
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 6,744 of the 17,000 delay minutes reported 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
7.0% 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 close to two hours, 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 8am–11am window matters as much as it does.
The return leg runs 81.5% 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 IAD to CLT
Put together: the delay figures matter less here than the 3.21% cancellation rate. A late arrival costs you close to two hours; 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. 933 completed flights over 12 months sit behind that.
