DL 1736 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 326 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1736 runs 8 points behind the country as a whole. Across a thousand flights that is about 76 extra late arrivals.

These figures cover 326 flights between July 2025 and June 2026. Beyond the headline rate, 12.4% 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 1736 flies

DL 1736 flies ATL to RSW without a single fixed slot. Its most common scheduled departure was 19:59, used on 81 of 326 flights, with 19:35 (55 flights) and 18:59 (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 19:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 1736 runs level with that at 70.0%. 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 1736 quarter by quarter

Quarter by quarter DL 1736 held fairly steady: 71.1% in Jul–Sep 2025, 69.8% in Oct–Dec 2025, 66.3% in Jan–Mar 2026 and 72.5% 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 1736 did best on Wednesday at 85.0% on time and worst on Sunday at 54.0%. Each day rests on about 47 flights, so a gap of 31 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1736 runs late

One category carries most of the weight here. Carrier accounts for 54% of the 5,998 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.

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 3,257 of the 5,998 delay minutes reported here. The split is drawn from 5,998 delay minutes reported on DL 1736.

Cancellations sit at 0.92% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 12.4% 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.

Every one of the 326 flights under DL 1736 in the data flew ATL to RSW. 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. 326 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 1736

For a booking, DL 1736 is a flight to put a long connection behind. 12.4% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
