Across the year

UA 698 quarter by quarter

UA 698 did not run the same all year. Its best quarter was Apr–Jun 2026 at 85.9% on time and its weakest Jul–Sep 2026 at 75.0%, a swing of 11 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.

By weekday, UA 698 did best on Tuesday at 89.4% on time and worst on Sunday at 76.6%. Each day rests on about 48 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 698 runs late

Late-arriving aircraft accounts for 59% of the 4,186 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    59%
  • Carrier
    34%
  • National Airspace System
    7%

59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,186 reported delay minutes here, that single category outweighs weather by 59 to one. The split is drawn from 4,186 delay minutes reported on UA 698.

Cancellations run at 2.66%, against 1.89% nationally. That is about one flight in 40 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

8.2% of arrivals land an hour or more late, close to the national 8.3%, so 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.

At 2,565 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 ONT to SFO (47), DCA to SFO (24) and ORD to ONT (3), but none flew often enough under UA 698 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to EWR only.

One caution: this is a thin sample. 338 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 698

For a booking, the cancellation rate is the figure to plan around on UA 698: 2.66% of its 338 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
