OH 5149 lands a B−, 3 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 2.7 hours on average.

These figures cover 354 flights between July 2025 and June 2026. Beyond the headline rate, 10.1% 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 5149 flies

OH 5149 flies TYS to DCA without a single fixed slot. Its most common scheduled departure was 06:00, used on 116 of 354 flights, with 06:05 (55 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OH 5149 runs 9 points worse at 80.4%. 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 5149 quarter by quarter

By weekday, OH 5149 did best on Sunday at 87.0% on time and worst on Monday at 66.0%. Each day rests on about 51 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why OH 5149 runs late

One category carries most of the weight here. Carrier accounts for 59% of the 11,000 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.

Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 10,799 delay minutes reported on OH 5149.

Cancellations run at 3.95%, against 1.81% nationally. That is about one flight in 25 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. 10.1% 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 354 flights under OH 5149 in the data flew TYS 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. 354 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 5149

For a booking, the cancellation rate is the figure to plan around on OH 5149: 3.95% of its 354 scheduled flights did not operate. A late arrival costs about 2.7 hours, but a cancellation costs the day, so leave a later option open.
