Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2836, check with Delta Air Lines.

DL 2836 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 356 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 2836's record is 7 points better than the US average of 77.6%. That gap is worth roughly 70 fewer late arrivals for every thousand flights.

These figures cover 356 flights between July 2025 and June 2026. The median arrival is 9 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 2836 flies

DL 2836 flies MIA to ATL without a single fixed slot. Its most common scheduled departure was 10:28, used on 72 of 356 flights, with 10:33 (68 flights) and 10:40 (48 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 10:3368 flights19.1%
  • Departs 10:4048 flights13.5%

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 10:28 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 2836 runs level with that at 84.6%. 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 2836 quarter by quarter

Quarter by quarter DL 2836 held fairly steady: 84.3% in Jul–Sep 2025, 84.7% in Oct–Dec 2025, 80.5% in Jan–Mar 2026 and 88.8% 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 2836 did best on Friday at 92.0% on time and worst on Saturday at 73.8%. Each day rests on about 51 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2836 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 4,842 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
    50%
  • Late-arriving aircraft
    37%
  • National Airspace System
    13%

37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,842 reported delay minutes here, that single category outweighs weather by 37 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,842 delay minutes reported on DL 2836.

Cancellations sit at 1.69% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

The 594 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.

DL 2836 is not only a MIA to ATL flight. It also flew ATL to MIA (342 flights, 88.6% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 356 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.
