Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1607, check with United Airlines.
UA 1607 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 7 minutes early.
Set against the rest of the country, UA 1607's record is 5 points better than the US average of 77.6%. That gap is worth roughly 49 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 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.
Schedule
When UA 1607 flies
UA 1607 flies IND to DEN without a single fixed slot. Its most common scheduled departure was 08:00, used on 166 of 365 flights, with 09:00 (60 flights) and 09:12 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1607 runs level with that at 82.5%. 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 1607 quarter by quarter
UA 1607 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.8% on time and its weakest Oct–Dec 2025 at 77.8%, a swing of 10 points on roughly 91 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.

- Oct–Dec 202592 flights77.8%
- Jan–Mar 202690 flights80.0%
- Apr–Jun 202691 flights87.8%
Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1607 did best on Wednesday at 86.5% on time and worst on Friday at 73.5%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1607 runs late
One category carries most of the weight here. Carrier accounts for 45% of the 3,674 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 45%Carrier
- 28%Late-arriving aircraft
- 22%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,644 of the 3,674 delay minutes reported here. The split is drawn from 3,674 delay minutes reported on UA 1607.
Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 976 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 365 flights under UA 1607 in the data flew IND 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.
