These figures cover 284 flights between July 2025 and June 2026. Beyond the headline rate, 10.6% 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 1568 flies

UA 1568 flies ORD to ROC without a single fixed slot. Its most common scheduled departure was 18:20, used on 54 of 284 flights, with 18:08 (37 flights) and 18:02 (36 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 18:20 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 1568 runs 5 points worse at 62.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

UA 1568 quarter by quarter

UA 1568 did not run the same all year. Its best quarter was Oct–Dec 2025 at 68.2% on time and its weakest Apr–Jun 2026 at 53.9%, a swing of 14 points on roughly 95 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 202585 flights68.2%

By weekday, UA 1568 ranged from 56.1% on Sunday to 67.6% on Saturday. With about 41 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 1568 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 7,049 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.

  • Late-arriving aircraft
    49%
  • Carrier
    24%
  • National Airspace System
    21%
  • Extreme weather
    6%

49% 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 7,049 reported delay minutes here, that single category outweighs weather by 8 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 7,049 delay minutes reported on UA 1568.

Cancellations are rare at 0.70%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

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. 10.6% 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.

The 528 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 six other city pairs in the data, including SFO to ORD (158), DSM to ORD (153) and IAD to BZN (6), but none flew often enough under UA 1568 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to ROC only.

One caution: this is a thin sample. 284 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 1568

For a booking, UA 1568 is one of the weaker ways to fly ORD to ROC: 11 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
