These figures cover 342 flights between July 2025 and June 2026. Beyond the headline rate, 11.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 2191 flies
UA 2191 flies EWR to LAX without a single fixed slot. Its most common scheduled departure was 14:45, used on 129 of 342 flights, with 14:10 (93 flights) and 14:15 (72 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 14:45 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 2191 runs 3 points better at 75.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 2191 quarter by quarter
UA 2191 did not run the same all year. Its best quarter was Apr–Jun 2026 at 83.5% on time and its weakest Oct–Dec 2025 at 69.2%, a swing of 14 points on roughly 86 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.

- Oct–Dec 202592 flights69.2%
- Jan–Mar 202690 flights78.2%

By weekday, UA 2191 did best on Tuesday at 83.7% on time and worst on Sunday at 67.4%. Each day rests on about 49 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2191 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 6,922 reported delay minutes.
- 41%Carrier
- 40%Late-arriving aircraft
- 15%National Airspace System
- 4%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,922 reported delay minutes here, that single category outweighs weather by 10 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,922 delay minutes reported on UA 2191.
Cancellations sit at 1.17% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 2,454 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 two other city pairs in the data, including LAX to PHX (49) and ORD to STL (23), but none flew often enough under UA 2191 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to LAX only.
One caution: this is a thin sample. 342 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 2191
