These figures cover 340 flights between July 2025 and June 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.
Schedule
When UA 2182 flies
UA 2182 flies IAH to ORD without a single fixed slot. Its most common scheduled departure was 07:20, used on 229 of 340 flights, with 07:25 (49 flights) and 07:24 (38 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 2182 runs level with that at 88.8%. 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 2182 quarter by quarter

By weekday, UA 2182 did best on Thursday at 95.8% on time and worst on Sunday at 83.7%. Each day rests on about 49 flights, so a gap of 12 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2182 runs late
One category carries most of the weight here. National Airspace System accounts for 58% of the 2,359 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.
- 58%National Airspace System
- 41%Carrier
- 1%Late-arriving aircraft
The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 969 of the 2,359 delay minutes reported here. The split is drawn from 2,359 delay minutes reported on UA 2182.
Cancellations are rare at 0.29%, 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
Badly late arrivals are rare here: only 4.1% 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 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.
UA 2182 is not only a IAH to ORD flight. It also flew ORD to PHL (325 flights, 77.1% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 340 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 2182
