UA 382 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%.

These figures cover 316 flights between July 2025 and June 2026. The median arrival is 20 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 382 flies
UA 382 flies DCA to IAH without a single fixed slot. Its most common scheduled departure was 12:40, used on 106 of 316 flights, with 12:50 (74 flights) and 12:59 (35 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 12:40 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 382 runs 12 points better at 90.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 382 quarter by quarter
UA 382 did not run the same all year. Its best quarter was Oct–Dec 2025 at 94.6% on time and its weakest Apr–Jun 2026 at 83.3%, a swing of 11 points on roughly 79 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 382 did best on Tuesday at 97.8% on time and worst on Friday at 84.1%. Each day rests on about 45 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 382 runs late
One category carries most of the weight here. National Airspace System accounts for 43% of the 3,193 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.
- 43%National Airspace System
- 42%Carrier
- 15%Late-arriving aircraft
The largest share of delay minutes, 42%, 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 1,335 of the 3,193 delay minutes reported here. The split is drawn from 3,193 delay minutes reported on UA 382.
Cancellations are rare at 0.32%, 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 4.5% 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 1,208 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 six other city pairs in the data, including IAH to SFO (139), IAH to SEA (63) and ORD to DCA (51), but none flew often enough under UA 382 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to IAH only.
One caution: this is a thin sample. 316 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 382
For a booking, UA 382 has one of the better records a US domestic flight can show: 90.7% on time and 0.32% cancelled. That is a base rate, not a promise about any single day.
