OH 5389 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 316 flights, with a median arrival 13 minutes early.

Set against the rest of the country, OH 5389's record is 7 points better than the US average of 77.6%. That gap is worth roughly 68 fewer late arrivals for every thousand flights.

These figures cover 316 flights between July 2025 and June 2026. The median arrival is 13 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 5389 flies

OH 5389 flies CLT to SBN without a single fixed slot. Its most common scheduled departure was 09:05, used on 44 of 316 flights, with 10:25 (37 flights) and 09:20 (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 09:05 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OH 5389 runs level with that at 84.4%. 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 5389 quarter by quarter

OH 5389 did not run the same all year. Its best quarter was Jul–Sep 2025 at 87.8% on time and its weakest Apr–Jun 2026 at 69.6%, a swing of 18 points on roughly 79 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.

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, OH 5389 ranged from 79.5% on Sunday to 91.1% on Wednesday. With about 45 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OH 5389 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 2,647 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.

Extreme weather
3%

45% 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 2,647 reported delay minutes here, that single category outweighs weather by 17 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 2,647 delay minutes reported on OH 5389.

Cancellations run at 2.85%, against 1.81% nationally. That is roughly one flight in 40 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

5.5% 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 about an hour, which a normal layover absorbs.

The 534 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.

OH 5389 is not only a CLT to SBN flight. It also flew SBN to CLT (316 flights, 80.4% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 316 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.
