These figures cover 261 flights between September 2025 and August 2026. The median arrival is 10 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.

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,520 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 4,520 delay minutes reported on OO 5084.

Cancellations sit at 1.15% against a national 1.89%, which is ordinary. Diversions add another 0.38%.

Connections and routes

What a delay on this flight costs

7.8% 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 close to two hours, which a normal layover absorbs.

The same number turns up on five other city pairs in the data, including PIR to DEN (104), LAR to DEN (27) and DEN to JLN (13), but none flew often enough under OO 5084 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to PIR only.

One caution: this is a thin sample. 261 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.
