These figures cover 355 flights between July 2025 and June 2026. The median arrival is 10 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 2600 flies
UA 2600 flies IAH to LAX without a single fixed slot. Its most common scheduled departure was 07:20, used on 145 of 355 flights, with 07:25 (65 flights) and 07:32 (49 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 07:20 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2600 runs 3 points better at 91.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route

Across the year
UA 2600 quarter by quarter
Quarter by quarter UA 2600 held fairly steady: 96.7% in Jul–Sep 2025, 93.5% in Oct–Dec 2025, 87.5% in Jan–Mar 2026 and 89.0% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights96.7%
- Oct–Dec 202592 flights93.5%
- Jan–Mar 202680 flights87.5%
- Apr–Jun 202691 flights89.0%
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2600 ranged from 88.5% on Saturday to 98.1% on Sunday. With about 51 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 2600 runs late
One category carries most of the weight here. Carrier accounts for 43% of the 1,107 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.
- 43%Carrier
- 33%National Airspace System
- 25%Late-arriving aircraft
33% 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 361 minutes out of 1,107, against a national NAS share of 21%. The split is drawn from 1,107 delay minutes reported on UA 2600.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 1.4% land an hour or more behind schedule, against 8.1% 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 1,379 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.
The same number turns up on one other city pair in the data, including RSW to LAX (10), but none flew often enough under UA 2600 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to LAX only.
One caution: this is a thin sample. 355 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 2600
For a booking, UA 2600 has one of the better records a US domestic flight can show: 91.8% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
