These figures cover 344 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.

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 344 flights, with 09:10 (82 flights) and 09:00 (80 flights) next.

A 09:05 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 1994 runs level with that at 84.0%. 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 96.7% on time and its weakest Jan–Mar 2026 at 74.4%, a swing of 22 points on roughly 69 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 1994 did best on Monday at 90.0% on time and worst on Sunday at 77.6%. Each day rests on about 49 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late UA 1994 runs when it is late

UA 1994 often beats the schedule: 90 of 344 completed flights, 26%, arrived 15 minutes or more early. Most of the lateness is short. 29 of the 55 late arrivals were under half an hour behind, and 10 reached an hour or more.

Share of 344 completed flights by arrival against schedule.

A late pushback is often recovered here: of 55 departures that left 15 minutes late or more, 22 still arrived on time. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PDX.

The latest arrival of the period was on 7 December 2025, 3 hours 32 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in April 2026.

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 2,669 reported delay minutes.

Carrier
38%
Late-arriving aircraft
24%
National Airspace System
23%
Extreme weather
16%

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 2,669 delay minutes reported on UA 1994.

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

Badly late arrivals are rare here: only 2.9% land an hour or more behind schedule, against 8.3% 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 RIC to ORD (36), CVG to ORD (32) and LAS to IAH (21), 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. 344 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

For a booking, read UA 1994 as 84.0% on time with 0.00% cancelled over 344 flights. Those are rates from the past twelve months, not a forecast for any particular day.
