These figures cover 322 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When UA 2417 flies

UA 2417 flies IAH to ORD without a single fixed slot. Its most common scheduled departure was 11:55, used on 214 of 322 flights, with 12:10 (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 11:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 2417 runs 3 points worse at 75.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

UA 2417 next to IAH to ORD

Across the year

UA 2417 quarter by quarter

Quarter by quarter UA 2417 held fairly steady: 76.9% in Jul–Sep 2025, 74.7% in Oct–Dec 2025, 76.9% in Jan–Mar 2026 and 73.8% in Apr–Jun 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202592 flights74.7%
Jan–Mar 202653 flights76.9%

Scale runs 65% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2417 did best on Tuesday at 87.0% on time and worst on Friday at 65.2%. Each day rests on about 46 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2417 runs late

One category carries most of the weight here. National Airspace System accounts for 47% of the 5,063 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.

47%
Late-arriving aircraft
24%
Carrier
21%
Extreme weather
8%

47% 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 2,367 minutes out of 5,063, against a national NAS share of 21%. The split is drawn from 5,063 delay minutes reported on UA 2417.

Cancellations are rare at 0.62%, below the national 1.81% 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

8.5% 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 925 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 seven other city pairs in the data, including ORD to SAN (172), MCO to IAH (86) and EWR to IAH (37), but none flew often enough under UA 2417 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to ORD only.

One caution: this is a thin sample. 322 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.
