Historical statistics for July 2025 to June 2026, not live status. For today’s DL 572, check with Delta Air Lines.
DL 572 lands a B−, 4 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 328 flights, with a median arrival 7 minutes early.

These figures cover 328 flights between July 2025 and June 2026. The median arrival is 7 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.
Schedule
When DL 572 flies
DL 572 flies LGA to MCI without a single fixed slot. Its most common scheduled departure was 08:30, used on 93 of 328 flights, with 07:40 (58 flights) and 07:30 (47 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 08:3093 flights28.4%

- Departs 07:3047 flights14.3%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
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 84.1%, and DL 572 runs 3 points worse at 81.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
DL 572 next to LGA to MCI
Every carrier on LGA to MCI combined arrived on time 68.7% of the time across 1,796 flights, so DL 572 is 13 points ahead of it. Delta flew 975 flights on the same city pair under all its flight numbers, including this one, and those ran 70.1% on time. Across its whole network Delta Air Lines managed 81.6%, close to this flight's figure.

Across the year
DL 572 quarter by quarter
DL 572 did not run the same all year. Its best quarter was Jul–Sep 2025 at 91.5% on time and its weakest Oct–Dec 2025 at 64.5%, a swing of 27 points on roughly 82 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.
- Jul–Sep 202584 flights91.5%
- Oct–Dec 202580 flights64.5%
- Jan–Mar 202682 flights83.6%
- Apr–Jun 202682 flights84.6%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 572 did best on Saturday at 91.4% on time and worst on Sunday at 72.5%. Each day rests on about 47 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 572 runs late
One category carries most of the weight here. Carrier accounts for 46% of the 4,210 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.
- 46%Carrier
- 27%Late-arriving aircraft
- 25%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,951 of the 4,210 delay minutes reported here. The split is drawn from 4,210 delay minutes reported on DL 572.
Cancellations run at 5.49%, against 1.81% nationally. That is roughly one flight in twenty 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
5.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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. 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 five other city pairs in the data, including MCI to LGA (165), 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. 328 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: 5.49% of its 328 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.
