These figures cover 340 flights between September 2025 and August 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.

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 88.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Share of 339 completed flights by arrival against schedule.
5 of 26 late departures made up the time and arrived on time, 19% of them. In the other direction, 18 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 2182
The latest arrival of the period was on 19 August 2026, 5 hours 33 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 August 2026 | 5 hours 33 minutes | Carrier |
| 7 December 2025 | 3 hours 16 minutes | National Airspace System |
| 31 December 2025 | 3 hours 9 minutes | Carrier |

Delay causes
Why UA 2182 runs late
National Airspace System accounts for 51% of the 2,563 delay minutes carriers reported here, and the remaining four split what is left.
- 51%National Airspace System
- 37%Carrier
- 12%Late-arriving aircraft
The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 946 of the 2,563 delay minutes reported here. The split is drawn from 2,563 delay minutes reported on UA 2182.
Cancellations are rare at 0.00%, below the national 1.89% 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 4.1% 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 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.
UA 2182 is not only a IAH to ORD flight. It also flew ORD to PHL (304 flights, 76.8% 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.

Booking UA 2182
