Across the year

UA 2238 quarter by quarter

UA 2238 did not run the same all year. Its best quarter was Oct–Dec 2025 at 73.3% on time and its weakest Jul–Sep 2026 at 56.4%, a swing of 17 points on roughly 91 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 2238 did best on Thursday at 76.0% on time and worst on Wednesday at 62.7%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Share of 349 completed flights by arrival against schedule.

30 of 119 late departures made up the time and arrived on time, 25% of them. In the other direction, 19 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 2238 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 9,986 reported delay minutes.

Late-arriving aircraft
38%
Carrier
34%
National Airspace System
17%
Extreme weather
11%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,986 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 9,986 delay minutes reported on UA 2238.

Cancellations run at 3.31%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

14.0% 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 three other city pairs in the data, including SAV to EWR (41), LAX to RNO (34) and MSO to ORD (1), but none flew often enough under UA 2238 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. 363 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 2238

For a booking, the cancellation rate is the figure to plan around on UA 2238: 3.31% of its 363 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
