Historical statistics for July 2025 to June 2026, not live status. For today’s DL 370, check with Delta Air Lines.

DL 370 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 287 flights, with a median arrival 14 minutes early.

Set against the rest of the country, DL 370's record is 11 points better than the US average of 77.6%. That gap is worth roughly 113 fewer late arrivals for every thousand flights.

These figures cover 287 flights between July 2025 and June 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 224 of 287 flights. 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 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 88.9%. 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 370 next to MCI to LGA

Every carrier on MCI to LGA combined arrived on time 77.0% of the time across 1,796 flights, so DL 370 is 12 points ahead of it. Delta flew 975 flights on the same city pair under all its flight numbers, including this one, and those ran 77.5% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 7 points.

Across the year

DL 370 quarter by quarter

Quarter by quarter DL 370 held fairly steady: 87.6% in Jul–Sep 2025, 93.4% in Oct–Dec 2025 and 88.4% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights87.6%

By weekday, DL 370 did best on Saturday at 97.5% on time and worst on Sunday at 75.0%. Each day rests on about 41 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 370 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,633 reported delay minutes.

Carrier
40%
Late-arriving aircraft
36%
National Airspace System
19%
Extreme weather
5%

36% 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 2,633 reported delay minutes here, that single category outweighs weather by 7 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 2,633 delay minutes reported on DL 370.

Cancellations run at 5.23%, against 1.81% nationally. That is about 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

6.3% 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 an hour and a half, 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 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: 5.23% 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.
