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 Jul–Sep 2026 at 57.1%, a swing of 26 points on roughly 85 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.

Share of 332 completed flights by arrival against schedule.
A late pushback is often recovered here: of 98 departures that left 15 minutes late or more, 30 still arrived on time. In the other direction, 18 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 LAX.

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 6,582 reported delay minutes.
- 41%Carrier
- 39%Late-arriving aircraft
- 19%National Airspace System
- 1%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,582 reported delay minutes here, that single category outweighs weather by 39 to one. The split is drawn from 6,582 delay minutes reported on UA 2191.
Cancellations sit at 2.06% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
Connections and routes
What a delay on this flight costs
11.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 one other city pair in the data, including 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. 340 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
