Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2164, check with United Airlines.

UA 2164 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 about an hour. That rests on 252 flights, with a median arrival 5 minutes early.

Set against the rest of the country, UA 2164's record is 8 points better than the US average of 77.6%. That gap is worth roughly 78 fewer late arrivals for every thousand flights.

These figures cover 252 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 2164 flies

UA 2164 is scheduled to leave Newark (EWR) at 06:00 local time and reach Chicago (ORD) at 07:38. That slot held for 251 of the 252 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2164 runs 4 points worse at 85.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 2164 next to EWR to ORD

Across the year

UA 2164 quarter by quarter

Quarter by quarter UA 2164 held fairly steady: 89.0% in Jul–Sep 2025, 83.7% in Oct–Dec 2025 and 84.1% in Jan–Mar 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202686 flights84.1%

By weekday, UA 2164 did best on Tuesday at 97.1% on time and worst on Friday at 80.6%. Each day rests on about 36 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2164 runs late

One category carries most of the weight here. National Airspace System accounts for 47% of the 2,048 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.

National Airspace System
47%
Carrier
35%
Late-arriving aircraft
18%

The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 725 of the 2,048 delay minutes reported here. The split is drawn from 2,048 delay minutes reported on UA 2164.

Cancellations sit at 1.98% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.8% 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.

The 719 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 eight other city pairs in the data, including ORD to PHX (98), ORD to CLE (37) and ORD to ABQ (37), but none flew often enough under UA 2164 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to ORD only.

One caution: this is a thin sample. 252 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.
