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.

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 1607 runs level with that at 84.8%. 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

7 of 41 late departures made up the time and arrived on time, 17% of them. In the other direction, 21 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.

Worst days for UA 1607
The latest arrival of the period was on 19 July 2026, 8 hours 8 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 July 2026 | 8 hours 8 minutes | Carrier |
| 30 May 2026 | 2 hours 51 minutes | Carrier |
| 22 February 2026 | 2 hours 17 minutes | Carrier |

Delay causes
Why UA 1607 runs late
Carrier accounts for 59% of the 2,971 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Carrier
- 26%National Airspace System
- 10%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,767 of the 2,971 delay minutes reported here. The split is drawn from 2,971 delay minutes reported on UA 1607.
Cancellations are rare at 0.82%, 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
Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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.
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.
What to do with this
Booking UA 1607
