These figures cover 365 flights between September 2025 and August 2026. The median arrival is 13 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 724 flies
UA 724 is scheduled to leave El Paso (ELP) at 07:00 local time and reach Denver (DEN) at 08:55. That slot held for 346 of the 365 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 724 runs 3 points better at 91.9%. 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 724 quarter by quarter
UA 724 did not run the same all year. Its best quarter was Jul–Sep 2025 at 100.0% on time and its weakest Apr–Jun 2026 at 86.7%, 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.

By weekday, UA 724 did best on Monday at 96.2% on time and worst on Friday at 84.0%. Each day rests on about 52 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

- 77%Carrier
- 17%Late-arriving aircraft
- 6%National Airspace System
The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,818 of the 3,665 delay minutes reported here. The split is drawn from 3,665 delay minutes reported on UA 724.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.6% 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 563 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.
The same number turns up on one other city pair in the data, including DEN to ATL (21), but none flew often enough under UA 724 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ELP to DEN only.
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 724
For a booking, UA 724 has one of the better records a US domestic flight can show: 91.9% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
