- 3%Extreme weather
The largest share of delay minutes, 60%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,782 of the 7,988 delay minutes reported here. The split is drawn from 7,988 delay minutes reported on OH 5031.

Connections and routes
What a delay on this flight costs
8.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
Every one of the 363 flights under OH 5031 in the data flew GSP 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. 363 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 5031
For a booking, the cancellation rate is the figure to plan around on OH 5031: 3.03% of its 363 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
