Carrier accounts for 62% of the 5,547 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 28%Late-arriving aircraft
- 8%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,461 of the 5,547 delay minutes reported here. The split is drawn from 5,547 delay minutes reported on OH 5578.
Cancellations run at 3.86%, against 1.89% 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
9.3% 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.
The 507 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.
Every one of the 337 flights under OH 5578 in the data flew CVG to PHL. 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. 337 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 5578
For a booking, the cancellation rate is the figure to plan around on OH 5578: 3.86% of its 337 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
