These figures cover 354 flights between September 2025 and August 2026. The median arrival is 10 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.

Across the year

DL 2836 quarter by quarter

DL 2836 did not run the same all year. Its best quarter was Jul–Sep 2026 at 94.7% on time and its weakest Jan–Mar 2026 at 80.5%, a swing of 14 points on roughly 89 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 2836 did best on Friday at 98.0% on time and worst on Sunday at 73.9%. Each day rests on about 51 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2836 runs late

Carrier accounts for 52% of the 3,568 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
52%
Late-arriving aircraft
32%
National Airspace System
16%

The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,860 of the 3,568 delay minutes reported here. The split is drawn from 3,568 delay minutes reported on DL 2836.

Cancellations run at 2.54%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.8% land an hour or more behind schedule, against 8.3% 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 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.

DL 2836 is not only a MIA to ATL flight. It also flew ATL to MIA (345 flights, 89.8% 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. 354 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 2836
