Historical statistics for July 2025 to June 2026, not live status. For today’s OH 5544, check with PSA Airlines. PSA Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OH 5544 earns a D−, which is as low as this site's scale goes for a reason. Only 57.1% of flights arrive inside the 15-minute window, 20 points worse than the national rate of 77.6%. Late arrivals average close to two hours. Treat any tight connection here as a coin flip. That rests on 359 flights, with a median arrival 8 minutes late.

The national on-time rate over the same period is 77.6%, so OH 5544 runs 20 points behind the country as a whole. Across a thousand flights that is about 205 extra late arrivals.

These figures cover 359 flights between July 2025 and June 2026. Beyond the headline rate, 24.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When OH 5544 flies

OH 5544 flies DCA to PNS without a single fixed slot. Its most common scheduled departure was 19:45, used on 213 of 359 flights, with 19:49 (54 flights) and 19:59 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 19:45 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OH 5544 runs 11 points worse at 57.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

OH 5544 quarter by quarter

OH 5544 did not run the same all year. Its best quarter was Oct–Dec 2025 at 69.9% on time and its weakest Apr–Jun 2026 at 47.6%, a swing of 22 points on roughly 90 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, OH 5544 did best on Monday at 70.8% on time and worst on Sunday at 42.6%. Each day rests on about 51 flights, so a gap of 28 points is worth noticing but could still narrow in another year.

Delay causes

Why OH 5544 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 15,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Late-arriving aircraft
    51%
  • Carrier
    25%
  • National Airspace System
    18%
  • Extreme weather
    5%
  • Security
    0%

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 15,000 reported delay minutes here, that single category outweighs weather by 10 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 14,873 delay minutes reported on OH 5544.

Cancellations run at 6.13%, against 1.81% nationally. That is roughly 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 routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 24.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 816 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 359 flights under OH 5544 in the data flew DCA to PNS. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 359 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 OH 5544

For a booking, the cancellation rate is the figure to plan around on OH 5544: 6.13% of its 359 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
