Carrier by carrier
PSA against every carrier on CMH to DCA
PSA flew 453 of the 2,051 flights on CMH to DCA, about 22% of it. Its 70.6% on time is about level with the route as a whole at 69.2%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Envoy at 88.7% to Southwest at 57.9%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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.

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 27 points, against half a point between the best and worst carrier.
- 5am–8am84 flights88.2%
- 8am–11am160 flights79.2%
- 11am–2pm1 flights—
- 2pm–5pm185 flights61.3%
- 5pm–8pm23 flights—
- 8pm–5am—
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 88.2% of the time, against 61.3% for the afternoon window. That is 27 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 185 flights scheduled in it.

Share of 419 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 94 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 36 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 DCA.
The worst days
Worst days for PSA on CMH to DCA
The latest arrival of the period was on 5 August 2026, 24 hours 41 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 August 2026 | 24 hours 41 minutes | Carrier |
| 30 April 2026 | 23 hours 41 minutes | Carrier |
| 1 January 2026 | 21 hours 35 minutes | Carrier |

Delay causes
Why PSA runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 14,000 reported delay minutes.
- 37%Carrier
- 33%Late-arriving aircraft
- 29%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,998 of the 14,000 delay minutes reported here. The split is drawn from 13,556 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 88.2% on time here.
Cancellations run at 7.51%, against 1.89% nationally. That is roughly one flight in twelve 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.
At 323 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 is a different operation and performs like one: it runs 73.7% on time across 455 flights, 3 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 3 points of difference.
One caution: this is a thin sample. 453 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 CMH to DCA
Put together: the delay figures matter less here than the 7.51% cancellation rate. A late arrival costs you close to two hours; 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. 419 completed flights over 12 months sit behind that.
