Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1077, check with Delta Air Lines.

DL 1077 draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 270 flights, with a median arrival right on schedule.

The national on-time rate over the same period is 77.6%, so DL 1077 runs 14 points behind the country as a whole. Across a thousand flights that is about 144 extra late arrivals.

These figures cover 270 flights between July 2025 and June 2026. Beyond the headline rate, 16.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 1077 flies

DL 1077 flies FLL to LGA without a single fixed slot. Its most common scheduled departure was 15:10, used on 73 of 270 flights, with 15:08 (72 flights) and 17:35 (36 flights) next. 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 15:10 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1077 runs 9 points worse at 63.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 1077 next to FLL to LGA

Across the year

DL 1077 quarter by quarter

DL 1077 did not run the same all year. Its best quarter was Jul–Sep 2025 at 70.0% on time and its weakest Oct–Dec 2025 at 58.8%, a swing of 11 points on roughly 90 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 1077 did best on Saturday at 84.2% on time and worst on Sunday at 42.9%. Each day rests on about 39 flights, so a gap of 41 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1077 runs late

One category carries most of the weight here. National Airspace System accounts for 46% of the 6,855 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.

40% 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 6,855 reported delay minutes here, that single category outweighs weather by 12 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 6,855 delay minutes reported on DL 1077.

Cancellations run at 3.33%, against 1.81% nationally. That is about one flight in 30 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 1,076 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 three other city pairs in the data, including LGA to FLL (248), SFO to AUS (79) and AUS to SFO (79), but none flew often enough under DL 1077 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FLL to LGA only.

One caution: this is a thin sample. 270 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 1077

For a booking, the cancellation rate is the figure to plan around on DL 1077: 3.33% of its 270 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.
