UA 2205 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 354 flights, with a median arrival 15 minutes early.
Set against the rest of the country, UA 2205's record is 7 points better than the US average of 77.6%. That gap is worth roughly 72 fewer late arrivals for every thousand flights.

These figures cover 354 flights between July 2025 and June 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.
Schedule
When UA 2205 flies
UA 2205 flies CMH to IAH without a single fixed slot. Its most common scheduled departure was 06:30, used on 199 of 354 flights, with 06:10 (68 flights) and 06:15 (56 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 06:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2205 runs 5 points worse at 84.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route

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 89 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 ranged from 80.4% on Monday to 89.8% on Thursday. With about 51 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 2205 runs late
One category carries most of the weight here. Carrier accounts for 57% of the 4,055 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.
- 57%Carrier
- 24%National Airspace System
- 13%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 57%, 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 2,311 of the 4,055 delay minutes reported here. The split is drawn from 4,055 delay minutes reported on UA 2205.
Cancellations sit at 1.41% against a national 1.81%, 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 4.3% 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 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. 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 five other city pairs in the data, including IAH to SEA (94), 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. 354 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
