Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1334, check with Delta Air Lines.

DL 1334 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 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 342 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 1334's record is 12 points better than the US average of 77.6%. That gap is worth roughly 116 fewer late arrivals for every thousand flights.

These figures cover 342 flights between July 2025 and June 2026. The median arrival is 10 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 1334 flies

DL 1334 flies ATL to FLL without a single fixed slot. Its most common scheduled departure was 07:25, used on 189 of 342 flights, with 07:00 (141 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 07:25 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 1334 runs level with that at 89.2%. 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

Across the year

DL 1334 quarter by quarter

Quarter by quarter DL 1334 held fairly steady: 86.4% in Jul–Sep 2025, 90.5% in Oct–Dec 2025, 87.8% in Jan–Mar 2026 and 92.0% 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.

By weekday, DL 1334 ranged from 85.4% on Sunday to 93.6% on Thursday. With about 49 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1334 runs late

One category carries most of the weight here. Carrier accounts for 67% of the 1,746 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.

Carrier
67%
National Airspace System
19%
Extreme weather
14%

Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 1,746 delay minutes reported on DL 1334.

Cancellations sit at 2.05% against a national 1.81%, which is ordinary. Diversions add another 0.29%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 1.8% land an hour or more behind schedule, against 8.1% 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 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.

The same number turns up on one other city pair in the data, including FLL to ATL (150), but none flew often enough under DL 1334 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to FLL only.

One caution: this is a thin sample. 342 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 1334

For a booking, read DL 1334 as 89.2% on time with 2.05% cancelled over 342 flights. Those are rates from the past twelve months, not a forecast for any particular day.
