These figures cover 344 flights between September 2025 and August 2026. The median arrival is 7 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.

A 09:49 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 2446 runs level with that at 83.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

UA 2446 quarter by quarter

UA 2446 did not run the same all year. Its best quarter was Jul–Sep 2026 at 88.5% on time and its weakest Oct–Dec 2025 at 74.3%, a swing of 14 points on roughly 86 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 2446 did best on Wednesday at 91.8% on time and worst on Thursday at 72.0%. Each day rests on about 49 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2446 runs late

National Airspace System accounts for 45% of the 3,929 delay minutes carriers reported here, and the remaining four split what is left.

29%
Late-arriving aircraft
25%
Extreme weather
1%

45% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,783 minutes out of 3,929, against a national NAS share of 21%. The split is drawn from 3,929 delay minutes reported on UA 2446.

Cancellations are rare at 0.87%, 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

5.9% 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.

At 1,620 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

UA 2446 is not only a DEN to LGA flight. It also flew ONT to DEN (303 flights, 94.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 344 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.
