Across the year

DL 1014 quarter by quarter

DL 1014 did not run the same all year. Its best quarter was Apr–Jun 2026 at 77.0% on time and its weakest Oct–Dec 2025 at 51.5%, a swing of 26 points on roughly 75 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, DL 1014 did best on Monday at 76.1% on time and worst on Thursday at 57.1%. Each day rests on about 43 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late DL 1014 runs when it is late

DL 1014 often beats the schedule: 131 of 283 completed flights, 46%, arrived 15 minutes or more early. The 87 late arrivals split 25 under half an hour, 22 between 30 and 60 minutes, and 40 an hour or more.

Share of 283 completed flights by arrival against schedule.

18 of 90 late departures made up the time and arrived on time, 20% of them. In the other direction, 15 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 DTW.

The worst days

Worst days for DL 1014

The latest arrival of the period was on 3 July 2026, 15 hours 42 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

Delay causes

Why DL 1014 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 8,887 reported delay minutes.

Late-arriving aircraft
40%
Carrier
39%
National Airspace System
21%

40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,887 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 8,887 delay minutes reported on DL 1014.

Cancellations run at 5.35%, against 1.89% 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

14.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

The 502 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 four other city pairs in the data, including JFK to SAT (13), SAV to DTW (8) and DTW to SAV (8), but none flew often enough under DL 1014 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to DTW only.

One caution: this is a thin sample. 299 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 1014

For a booking, the cancellation rate is the figure to plan around on DL 1014: 5.35% of its 299 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
