These figures cover 355 flights between September 2025 and August 2026. The median arrival is 15 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.

Across the year
UA 2205 quarter by quarter
UA 2205 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.9% on time and its weakest Oct–Dec 2025 at 76.1%, a swing of 17 points on roughly 71 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 2205 did best on Thursday at 92.0% on time and worst on Saturday at 78.8%. Each day rests on about 51 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late UA 2205 runs when it is late
UA 2205 often beats the schedule: 183 of 349 completed flights, 52%, arrived 15 minutes or more early. The 55 late arrivals split 25 under half an hour, 13 between 30 and 60 minutes, and 17 an hour or more.

Share of 349 completed flights by arrival against schedule.
A late pushback is often recovered here: of 49 departures that left 15 minutes late or more, 18 still arrived on time. In the other direction, 24 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 IAH.

Delay causes
Why UA 2205 runs late

- 48%Carrier
- 23%National Airspace System
- 23%Late-arriving aircraft
- 7%Extreme weather
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,064 of the 4,344 delay minutes reported here. The split is drawn from 4,344 delay minutes reported on UA 2205.
Cancellations sit at 1.41% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.9% 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 986 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 three other city pairs in the data, including IAH to SEA (156), IAH to EGE (40) and SEA to SFO (23), but none flew often enough under UA 2205 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CMH to IAH 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 2205
For a booking, read UA 2205 as 84.2% on time with 1.41% cancelled over 355 flights. Those are rates from the past twelve months, not a forecast for any particular day.
