Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1124, check with Delta Air Lines.

DL 1124 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 350 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1124 runs 6 points behind the country as a whole. Across a thousand flights that is about 59 extra late arrivals.

These figures cover 350 flights between July 2025 and June 2026. Beyond the headline rate, 10.2% 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 1124 flies

DL 1124 flies ATL to RSW without a single fixed slot. Its most common scheduled departure was 22:55, used on 86 of 350 flights, with 23:07 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 22:55 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1124 runs level with that at 71.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

DL 1124 quarter by quarter

Quarter by quarter DL 1124 held fairly steady: 70.3% in Jul–Sep 2025, 75.0% in Oct–Dec 2025, 70.9% in Jan–Mar 2026 and 70.6% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1124 did best on Wednesday at 85.1% on time and worst on Sunday at 63.3%. Each day rests on about 50 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1124 runs late

One category carries most of the weight here. Carrier accounts for 54% of the 6,702 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
    54%
  • Late-arriving aircraft
    23%
  • National Airspace System
    20%
  • Extreme weather
    3%

The largest share of delay minutes, 54%, 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 3,612 of the 6,702 delay minutes reported here. The split is drawn from 6,702 delay minutes reported on DL 1124.

Cancellations sit at 1.43% against a national 1.81%, which is ordinary. Diversions add another 0.57%.

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. 10.2% 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 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 (93), but none flew often enough under DL 1124 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. 350 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 1124

For a booking, DL 1124 is one of the weaker ways to fly ATL to RSW: 6 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
