These figures cover 260 flights between September 2025 and August 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Delay causes
Why OO 5395 runs late
Carrier accounts for 49% of the 3,354 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 23%National Airspace System
- 22%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,653 of the 3,354 delay minutes reported here. The split is drawn from 3,354 delay minutes reported on OO 5395.
Cancellations run at 2.69%, against 1.89% nationally. That is about one flight in 40 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
6.7% 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 about an hour, which a normal layover absorbs.
The 589 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.
The same number turns up on two other city pairs in the data, including IAH to SHV (82) and ORD to FNT (21), but none flew often enough under OO 5395 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to GSO only.
One caution: this is a thin sample. 260 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 OO 5395
For a booking, the cancellation rate is the figure to plan around on OO 5395: 2.69% of its 260 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
