DL 2736 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 close to two hours on average.

These figures cover 265 flights between July 2025 and June 2026. Beyond the headline rate, 9.6% 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 2736 flies

DL 2736 flies AUS to DTW without a single fixed slot. Its most common scheduled departure was 16:40, used on 69 of 265 flights, with 16:00 (56 flights) and 16:46 (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 16:40 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2736 runs 8 points better at 80.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2736 quarter by quarter

Quarter by quarter DL 2736 held fairly steady: 81.4% in Jul–Sep 2025, 80.0% in Oct–Dec 2025, 83.3% in Jan–Mar 2026 and 76.3% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202565 flights80.0%
Jan–Mar 202680 flights83.3%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2736 did best on Tuesday at 90.7% on time and worst on Monday at 69.8%. Each day rests on about 38 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2736 runs late

One category carries most of the weight here. Carrier accounts for 60% of the 6,017 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
60%
Late-arriving aircraft
32%
National Airspace System
4%
Extreme weather
3%

The largest share of delay minutes, 60%, 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 3,611 of the 6,017 delay minutes reported here. The split is drawn from 6,017 delay minutes reported on DL 2736.

Cancellations are rare at 0.75%, 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. 9.6% 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 1,149 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 265 flights under DL 2736 in the data flew AUS to DTW. 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. 265 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
