Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1994, check with United Airlines.
UA 1994 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 316 flights, with a median arrival 6 minutes early.
Set against the rest of the country, UA 1994's record is 6 points better than the US average of 77.6%. That gap is worth roughly 59 fewer late arrivals for every thousand flights.

These figures cover 316 flights between July 2025 and June 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.
Schedule
When UA 1994 flies
UA 1994 flies ORD to PDX without a single fixed slot. Its most common scheduled departure was 09:05, used on 91 of 316 flights, with 09:10 (82 flights) and 09:00 (51 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 09:0591 flights28.8%
- Departs 09:1082 flights25.9%
- Departs 09:0051 flights16.1%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:05 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1994 runs level with that at 83.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
UA 1994 quarter by quarter
UA 1994 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.7% on time and its weakest Jan–Mar 2026 at 74.4%, a swing of 23 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.
- Jul–Sep 202543 flights97.7%
- Oct–Dec 202592 flights79.3%
- Jan–Mar 202690 flights74.4%
- Apr–Jun 202691 flights90.1%
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1994 ranged from 77.8% on Sunday to 88.9% on Monday. With about 45 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 1994 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,596 reported delay minutes.
- 37%Carrier
- 24%Late-arriving aircraft
- 23%National Airspace System
- 16%Extreme weather
Extreme weather accounts for 16% 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 2.6 times the usual weather exposure. The split is drawn from 2,596 delay minutes reported on UA 1994.
Cancellations are rare at 0.00%, below the national 1.81% 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
Badly late arrivals are rare here: only 3.2% 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.
At 1,739 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on four other city pairs in the data, including DEN to EWR (49), RIC to ORD (36) and CVG to ORD (32), but none flew often enough under UA 1994 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to PDX 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 1994
