These figures cover 325 flights between September 2025 and August 2026. The median arrival is 6 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 572 runs 3 points worse at 80.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 572 quarter by quarter
DL 572 did not run the same all year. Its best quarter was Jul–Sep 2026 at 85.4% on time and its weakest Oct–Dec 2025 at 64.5%, a swing of 21 points on roughly 81 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 202580 flights64.5%
- Jan–Mar 202682 flights83.6%
- Apr–Jun 202682 flights84.6%
- Jul–Sep 202653 flights85.4%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 572 did best on Friday at 91.1% on time and worst on Sunday at 72.1%. Each day rests on about 46 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 572 runs when it is late
DL 572 often beats the schedule: 105 of 303 completed flights, 35%, arrived 15 minutes or more early. The 58 late arrivals split 23 under half an hour, 16 between 30 and 60 minutes, and 19 an hour or more.

Share of 303 completed flights by arrival against schedule.
5 of 34 late departures made up the time and arrived on time, 15% of them. In the other direction, 29 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 MCI.
The worst days
Worst days for DL 572
The latest arrival of the period was on 3 December 2025, 5 hours 57 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 December 2025 | 5 hours 57 minutes | Late-arriving aircraft |
| 27 January 2026 | 5 hours 1 minute | Late-arriving aircraft |
| 6 December 2025 | 4 hours 46 minutes | Carrier |
| 13 October 2025 | 4 hours 30 minutes | Carrier |
| 3 November 2025 | 3 hours 55 minutes | Late-arriving aircraft |
Delay causes
Why DL 572 runs late
Carrier accounts for 47% of the 4,233 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Carrier
- 27%National Airspace System
- 24%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,009 of the 4,233 delay minutes reported here. The split is drawn from 4,233 delay minutes reported on DL 572.
Cancellations run at 6.15%, against 1.89% nationally. That is roughly one flight in fifteen 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
6.3% 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.
The 1,107 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.
The same number turns up on five other city pairs in the data, including MCI to LGA (217), DTW to PDX (16) and PDX to DTW (16), but none flew often enough under DL 572 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to MCI only.
One caution: this is a thin sample. 325 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 DL 572
For a booking, the cancellation rate is the figure to plan around on DL 572: 6.15% of its 325 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.
