These figures cover 365 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.

Across the year
UA 302 quarter by quarter
UA 302 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.6% on time and its weakest Jul–Sep 2026 at 75.0%, a swing of 13 points on roughly 73 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.

Share of 360 completed flights by arrival against schedule.
13 of 58 late departures made up the time and arrived on time, 22% of them. In the other direction, 23 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DEN.
The worst days
Worst days for UA 302
The latest arrival of the period was on 24 March 2026, 7 hours 15 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across March, August, January, December and February, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 March 2026 | 7 hours 15 minutes | Late-arriving aircraft |
| 6 August 2026 | 6 hours 2 minutes | Carrier |
| 1 January 2026 | 4 hours 14 minutes | Carrier |

Delay causes
Why UA 302 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 4,729 reported delay minutes.
- 37%National Airspace System
- 35%Carrier
- 26%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,647 of the 4,729 delay minutes reported here. The split is drawn from 4,729 delay minutes reported on UA 302.
Cancellations are rare at 0.27%, 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
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 a little over an hour, which a normal layover absorbs.
The 1,123 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.
Every one of the 365 flights under UA 302 in the data flew DTW to DEN. 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. 365 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
