These figures cover 320 flights between September 2025 and August 2026. The median arrival is 6 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 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 Jul–Sep 2026 at 70.0%, a swing of 23 points on roughly 80 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.
- Jul–Sep 202529 flights—
- Oct–Dec 202585 flights85.9%
- Jan–Mar 202668 flights92.6%
- Apr–Jun 202676 flights81.3%
- Jul–Sep 202662 flights70.0%
Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 358 did best on Tuesday at 92.2% on time and worst on Sunday at 69.4%. Each day rests on about 46 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

The worst days
Worst days for UA 358
The latest arrival of the period was on 10 May 2026, 21 hours 16 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 10 May 2026 | 21 hours 16 minutes | Late-arriving aircraft |
| 19 May 2026 | 4 hours 38 minutes | Late-arriving aircraft |
| 20 November 2025 | 4 hours 13 minutes | Late-arriving aircraft |

Delay causes
Why UA 358 runs late
Late-arriving aircraft accounts for 57% of the 4,646 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 17%Carrier
- 14%National Airspace System
- 12%Extreme weather
Extreme weather accounts for 12% 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 2.0 times the usual weather exposure. The split is drawn from 4,646 delay minutes reported on UA 358.
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
5.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, 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.
The same number turns up on eight other city pairs in the data, including IAH to DFW (228), 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. 320 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, read UA 358 as 83.6% on time with 0.00% cancelled over 320 flights. Those are rates from the past twelve months, not a forecast for any particular day.
