Historical statistics for July 2025 to June 2026, not live status. For today’s UA 358, check with United Airlines.

UA 358 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 295 flights, with a median arrival 7 minutes early.

Set against the rest of the country, UA 358's record is 8 points better than the US average of 77.6%. That gap is worth roughly 81 fewer late arrivals for every thousand flights.

These figures cover 295 flights between July 2025 and June 2026. The median arrival is 7 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 358 flies

UA 358 flies DFW to IAD without a single fixed slot. Its most common scheduled departure was 12:10, used on 105 of 295 flights, with 12:15 (42 flights) and 12:25 (39 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 12:10 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 358 runs 7 points better at 85.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 358 quarter by quarter

UA 358 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.6% on time and its weakest Apr–Jun 2026 at 81.3%, a swing of 11 points on roughly 74 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 358 did best on Tuesday at 93.9% on time and worst on Friday at 81.6%. Each day rests on about 42 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 358 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 58% of the 4,323 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.

19%
Extreme weather

National Airspace System
10%

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 4,323 delay minutes reported on UA 358.

Cancellations are rare at 0.34%, 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

5.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.

The 1,172 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 nine other city pairs in the data, including IAH to DFW (171), EGE to DEN (6) and CLE to EWR (4), but none flew often enough under UA 358 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to IAD only.

One caution: this is a thin sample. 295 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 358

For a booking, UA 358 has one of the better records a US domestic flight can show: 85.7% on time and 0.34% cancelled. That is a base rate, not a promise about any single day.
