Across the year
UA 2417 quarter by quarter
UA 2417 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.3% on time and its weakest Apr–Jun 2026 at 73.8%, a swing of 20 points on roughly 70 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 2417 did best on Tuesday at 90.0% on time and worst on Friday at 67.5%. Each day rests on about 40 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Share of 276 completed flights by arrival against schedule.
8 of 47 late departures made up the time and arrived on time, 17% of them. In the other direction, 25 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 ORD.
The worst days
Worst days for UA 2417
The latest arrival of the period was on 15 March 2026, 6 hours behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in March 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 March 2026 | 6 hours | National Airspace System |
| 6 March 2026 | 5 hours 37 minutes | Late-arriving aircraft |
| 15 November 2025 | 4 hours 33 minutes | Carrier |

Delay causes
Why UA 2417 runs late
National Airspace System accounts for 58% of the 4,435 delay minutes carriers reported here, and the remaining four split what is left.
- 58%National Airspace System
- 23%Late-arriving aircraft
- 14%Carrier
- 5%Extreme weather
58% 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 2,573 minutes out of 4,435, against a national NAS share of 21%. The split is drawn from 4,435 delay minutes reported on UA 2417.
Cancellations are rare at 0.71%, 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
8.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over 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.
The same number turns up on seven other city pairs in the data, including ORD to SAN (110), MIA to IAH (71) 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. 281 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 2417
