Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1489, check with Delta Air Lines.

DL 1489 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 355 flights, with a median arrival right on schedule.

The national on-time rate over the same period is 77.6%, so DL 1489 runs 9 points behind the country as a whole. Across a thousand flights that is about 91 extra late arrivals.

These figures cover 355 flights between July 2025 and June 2026. Beyond the headline rate, 11.1% 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 1489 flies

DL 1489 flies ATL to FLL without a single fixed slot. Its most common scheduled departure was 19:50, used on 67 of 355 flights, with 20:10 (63 flights) and 20:40 (53 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 19:50 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 1489 runs level with that at 68.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 1489 quarter by quarter

DL 1489 did not run the same all year. Its best quarter was Oct–Dec 2025 at 72.5% on time and its weakest Jan–Mar 2026 at 60.8%, a swing of 12 points on roughly 89 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 1489 did best on Saturday at 79.5% on time and worst on Sunday at 55.1%. Each day rests on about 51 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1489 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 6,402 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.

Extreme weather
6%

The largest share of delay minutes, 49%, 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 3,126 of the 6,402 delay minutes reported here. The split is drawn from 6,402 delay minutes reported on DL 1489.

Cancellations are rare at 0.85%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

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. 11.1% 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 581 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.

Every one of the 355 flights under DL 1489 in the data flew ATL to FLL. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 355 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.
