Delay causes
Why OH 5149 runs late
Carrier accounts for 61% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Carrier
- 16%Extreme weather
- 16%Late-arriving aircraft
- 7%National Airspace System
- 0%Security
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 2.7 times the usual weather exposure. The split is drawn from 10,364 delay minutes reported on OH 5149.
Cancellations run at 3.07%, against 1.89% nationally. That is roughly 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
9.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
Every one of the 358 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. 358 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: 3.07% of its 358 scheduled flights did not operate. A late arrival costs about 2.6 hours, but a cancellation costs the day, so leave a later option open.
