These figures cover 301 flights between September 2025 and August 2026. The median arrival is 5 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 5950 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,157 reported delay minutes.

Late-arriving aircraft
38%
Carrier
35%
National Airspace System
24%
Extreme weather
2%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,157 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 4,157 delay minutes reported on OO 5950.

Cancellations are rare at 0.33%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

7.0% 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 a little over an hour, which a normal layover absorbs.

The same number turns up on two other city pairs in the data, including DEN to MSO (49) and DSM to DEN (18), but none flew often enough under OO 5950 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to IDA only.

One caution: this is a thin sample. 301 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 5950

For a booking, read OO 5950 as 81.7% on time with 0.33% cancelled over 301 flights. Those are rates from the past twelve months, not a forecast for any particular day.
