Historical statistics for July 2025 to June 2026, not live status. For today’s OH 5031, 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 5031 lands a B−, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 345 flights, with a median arrival 7 minutes early.

These figures cover 345 flights between July 2025 and June 2026. The median arrival is 7 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.

Schedule

When OH 5031 flies

OH 5031 flies GSP to DCA without a single fixed slot. Its most common scheduled departure was 07:38, used on 45 of 345 flights, with 06:30 (43 flights) and 07:07 (36 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 07:38 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OH 5031 runs 13 points worse at 76.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OH 5031 quarter by quarter

OH 5031 did not run the same all year. Its best quarter was Oct–Dec 2025 at 87.4% on time and its weakest Jan–Mar 2026 at 60.9%, a swing of 27 points on roughly 86 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 5031 did best on Saturday at 82.0% on time and worst on Tuesday at 69.6%. Each day rests on about 49 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why OH 5031 runs late

One category carries most of the weight here. Carrier accounts for 57% of the 6,507 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
20%
National Airspace System
19%
Extreme weather
4%

The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,699 of the 6,507 delay minutes reported here. The split is drawn from 6,507 delay minutes reported on OH 5031.

Cancellations run at 3.48%, against 1.81% 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 routes

What a delay on this flight costs

7.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including MYR to DCA (1), but none flew often enough under OH 5031 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GSP to DCA only.

One caution: this is a thin sample. 345 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 5031

For a booking, the cancellation rate is the figure to plan around on OH 5031: 3.48% of its 345 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
