DL 1153 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 45 minutes on average. That is a workable record, not a spotless one. That rests on 363 flights, with a median arrival 4 minutes early.

These figures cover 363 flights between July 2025 and June 2026. The median arrival is 4 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 1153 flies

DL 1153 flies ATL to RSW without a single fixed slot. Its most common scheduled departure was 10:10, used on 109 of 363 flights, with 10:49 (41 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 10:10 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1153 runs 3 points worse at 80.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 1153 quarter by quarter

Quarter by quarter DL 1153 held fairly steady: 76.1% in Jul–Sep 2025, 84.1% in Oct–Dec 2025, 80.0% in Jan–Mar 2026 and 83.3% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1153 ranged from 77.1% on Sunday to 86.5% on Tuesday. With about 52 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1153 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 3,038 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
0%

The largest share of delay minutes, 56%, 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 1,697 of the 3,038 delay minutes reported here. The split is drawn from 3,038 delay minutes reported on DL 1153.

Cancellations sit at 2.20% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.4% 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 515 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 RSW to ATL (233), but none flew often enough under DL 1153 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to RSW only.

One caution: this is a thin sample. 363 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 1153
