These figures cover 287 flights between September 2025 and August 2026. The median arrival is 14 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 370 flies
DL 370 flies MCI to LGA without a single fixed slot. Its most common scheduled departure was 06:00, used on 226 of 287 flights.

Scale runs 0% to 100%.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 370 runs level with that at 90.7%. 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 370 quarter by quarter
Quarter by quarter DL 370 held fairly steady: 93.3% in Jul–Sep 2025, 93.4% in Oct–Dec 2025, 88.4% in Apr–Jun 2026 and 93.1% in Jul–Sep 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202530 flights93.3%
- Oct–Dec 202580 flights93.4%
- Jan–Mar 202624 flights—
- Apr–Jun 202691 flights88.4%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 370 did best on Friday at 97.4% on time and worst on Tuesday at 79.5%. Each day rests on about 41 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 370
The latest arrival of the period was on 19 May 2026, 7 hours 36 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 |
|---|---|---|
| 19 May 2026 | 7 hours 36 minutes | Late-arriving aircraft |
| 18 November 2025 | 4 hours 39 minutes | Late-arriving aircraft |
| 7 June 2026 | 3 hours 22 minutes | Late-arriving aircraft |
| 14 December 2025 | 2 hours 12 minutes | National Airspace System |

Delay causes
Why DL 370 runs late
Late-arriving aircraft accounts for 45% of the 2,097 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 28%Carrier
- 26%National Airspace System
- 2%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,097 reported delay minutes here, that single category outweighs weather by 29 to one. The split is drawn from 2,097 delay minutes reported on DL 370.
Cancellations run at 5.57%, against 1.89% 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
Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 two other city pairs in the data, including LAX to DTW (62) and RDU to SEA (16), but none flew often enough under DL 370 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MCI to LGA only.
One caution: this is a thin sample. 287 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 370
For a booking, the cancellation rate is the figure to plan around on DL 370: 5.57% of its 287 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
