Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on DCA to MYR lands a B−, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 583 flights, with a median arrival 4 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate PSA on DCA to MYR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
PSA against every carrier on DCA to MYR
PSA flew 583 of the 754 flights on DCA to MYR, most of the route. Its 76.4% on time is about level with the route as a whole at 76.0%. 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 54.2%. 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 18 points, against half a point between the best and worst carrier.
- 5am–8am—
- 8am–11am341 flights80.6%
- 11am–2pm112 flights76.0%
- 2pm–5pm84 flights67.5%
- 5pm–8pm46 flights63.0%
- 8pm–5am—
Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 63.0% on time, against 80.6% 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 8am–11am window is the busiest, with 341 flights scheduled in it.
Across the year
PSA on DCA to MYR through the year
January is the weak month at 62.5% on time, against 86.0% in November. 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. June was the busiest month here, with 62 flights.
Across the week, Monday is the strongest day at 84.8% on time and Thursday the weakest at 71.2%, a spread of 14 points.

Share of 551 completed flights by arrival against schedule.
33 of 133 late departures made up the time and arrived on time, 25% of them. In the other direction, 30 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 MYR.
The worst days
Worst days for PSA on DCA to MYR
The latest arrival of the period was on 5 December 2025, 4 hours 34 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as extreme weather.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 December 2025 | 4 hours 34 minutes | Late-arriving aircraft |
| 27 May 2026 | 4 hours 26 minutes | Extreme weather |
| 18 July 2026 | 4 hours 22 minutes | Extreme weather |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 55% of the 8,915 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 18%Carrier
- 16%National Airspace System
- 10%Extreme weather
- 1%Security
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,915 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 8,915 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 80.6% on time here.
Cancellations run at 5.49%, against 1.89% nationally. That is roughly 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
8.9% 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 a little over an hour, which a normal layover absorbs.
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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 70.1% on time across 582 flights, 6 points below 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. 583 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 MYR
Put together: the delay figures matter less here than the 5.49% 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. 551 completed flights over 12 months sit behind that.
