These figures cover 353 flights between July 2025 and June 2026. Beyond the headline rate, 18.9% 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 1564 flies
UA 1564 flies DFW to ORD without a single fixed slot. Its most common scheduled departure was 16:18, used on 80 of 353 flights, with 16:24 (53 flights) and 16:27 (49 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 16:18 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 1564 runs 14 points worse at 58.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 1564 quarter by quarter
UA 1564 did not run the same all year. Its best quarter was Oct–Dec 2025 at 62.2% on time and its weakest Jul–Sep 2025 at 51.6%, a swing of 11 points on roughly 88 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 1564 did best on Tuesday at 73.6% on time and worst on Thursday at 42.9%. Each day rests on about 50 flights, so a gap of 31 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1564 runs late
One category carries most of the weight here. National Airspace System accounts for 44% of the 13,000 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.
- 44%National Airspace System
- 38%Late-arriving aircraft
- 14%Carrier
- 4%Extreme weather
38% 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 13,000 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 13,356 delay minutes reported on UA 1564.
Cancellations are rare at 0.57%, 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. 18.9% 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 802 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 IAD to DFW (139), ORD to MSP (111) and ORD to SJC (24), but none flew often enough under UA 1564 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to ORD only.
One caution: this is a thin sample. 353 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 1564
For a booking, UA 1564 is a flight to put a long connection behind. 18.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
