Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1920, check with United Airlines.

UA 1920 lands a B, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 313 flights, with a median arrival 5 minutes early.

These figures cover 313 flights between July 2025 and June 2026. The median arrival is 5 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 1920 flies

UA 1920 flies RDU to ORD without a single fixed slot. Its most common scheduled departure was 13:30, used on 52 of 313 flights, with 13:15 (48 flights) and 13:28 (42 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 13:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1920 runs level with that at 78.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

UA 1920 next to RDU to ORD

Across the year

UA 1920 quarter by quarter

Quarter by quarter UA 1920 held fairly steady: 78.2% in Jul–Sep 2025, 73.3% in Oct–Dec 2025, 82.8% in Jan–Mar 2026 and 81.8% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202587 flights78.2%
Oct–Dec 202591 flights73.3%
Jan–Mar 202690 flights82.8%
Apr–Jun 202645 flights81.8%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1920 did best on Thursday at 86.4% on time and worst on Sunday at 69.8%. Each day rests on about 45 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1920 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 5,119 reported delay minutes.

National Airspace System
35%
Late-arriving aircraft
31%
Carrier
19%
Extreme weather
15%

Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 5,119 delay minutes reported on UA 1920.

Cancellations sit at 1.28% against a national 1.81%, which is ordinary. Diversions add another 0.32%.

Connections and routes

What a delay on this flight costs

7.1% 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 a little over an hour, which a normal layover absorbs.

The 646 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 seven other city pairs in the data, including ORD to SMF (217), ORD to LAS (73) and LAS to DEN (41), but none flew often enough under UA 1920 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDU to ORD only.

One caution: this is a thin sample. 313 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.
