Carrier by carrier
PSA against every carrier on MYR to DCA
PSA flew 582 of the 753 flights on MYR to DCA, most of the route. Its 70.1% on time is about level with the route as a whole at 70.6%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from American at 100.0% to Envoy at 47.8%. Three 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 19 points, against half a point between the best and worst carrier.

- 8am–11am46 flights73.8%
- 11am–2pm301 flights76.0%
- 2pm–5pm121 flights65.5%
- 5pm–8pm114 flights57.3%
- 8pm–5am—
Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 57.3% on time, against 76.0% for the 11am–2pm 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 301 flights scheduled in it.
Across the year
PSA on MYR to DCA through the year
May is the best month on the calendar at 88.1% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. June was the busiest month here, with 62 flights.
Across the week, Saturday is the strongest day at 73.7% on time and Sunday the weakest at 61.8%, a spread of 12 points.
Arrival by arrival
How late PSA on MYR to DCA runs when it is late
PSA on MYR to DCA often beats the schedule: 185 of 542 completed flights, 34%, arrived 15 minutes or more early. The 162 late arrivals split 40 under half an hour, 55 between 30 and 60 minutes, and 67 an hour or more.

Share of 542 completed flights by arrival against schedule.
20 of 142 late departures made up the time and arrived on time, 14% of them. In the other direction, 40 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 MYR to DCA
The latest arrival of the period was on 21 July 2026, 20 hours 51 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 |
|---|---|---|
| 21 July 2026 | 20 hours 51 minutes | Carrier |
| 22 June 2026 | 20 hours 11 minutes | Extreme weather |
| 22 July 2026 | 19 hours 45 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 18,000 reported delay minutes.
- 37%Late-arriving aircraft
- 25%Carrier
- 24%National Airspace System
- 13%Extreme weather
- 1%Security
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 17,713 reported delay minutes.
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 18,000 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 6.70%, 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
12.4% 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 372 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 76.4% on time across 583 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 582 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 MYR to DCA
Put together: the delay figures matter less here than the 6.70% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 542 completed flights over 12 months sit behind that.
