OH 5678 lands a B−, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 2.2 hours on average. That is a workable record, not a spotless one. That rests on 361 flights, with a median arrival 5 minutes early.

These figures cover 361 flights between July 2025 and June 2026. Beyond the headline rate, 9.4% 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 5678 flies

OH 5678 is scheduled to leave White Plains (HPN) at 06:30 local time and reach Washington (DCA) at 07:50. That slot held for 304 of the 361 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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

A 06:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OH 5678 runs 10 points worse at 79.5%. 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 5678 quarter by quarter

Quarter by quarter OH 5678 held fairly steady: 83.3% in Jul–Sep 2025, 79.5% in Oct–Dec 2025, 73.5% in Jan–Mar 2026 and 81.5% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, OH 5678 did best on Saturday at 89.6% on time and worst on Thursday at 74.0%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why OH 5678 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 9,192 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.

55%
Late-arriving aircraft
29%
National Airspace System
13%
Extreme weather
3%

The largest share of delay minutes, 55%, 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 5,074 of the 9,192 delay minutes reported here. The split is drawn from 9,192 delay minutes reported on OH 5678.

Cancellations run at 4.71%, against 1.81% nationally. That is about 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 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. 9.4% 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.

Every one of the 361 flights under OH 5678 in the data flew HPN to DCA. 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. 361 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 5678

For a booking, the cancellation rate is the figure to plan around on OH 5678: 4.71% of its 361 scheduled flights did not operate. A late arrival costs about 2.2 hours, but a cancellation costs the day, so leave a later option open.
