DL 1353 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 350 flights, with a median arrival 6 minutes early.

Set against the rest of the country, DL 1353's record is 10 points better than the US average of 77.6%. That gap is worth roughly 95 fewer late arrivals for every thousand flights.

These figures cover 350 flights between July 2025 and June 2026. The median arrival is 6 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 1353 flies

DL 1353 flies ATL to PIT without a single fixed slot. Its most common scheduled departure was 14:00, used on 36 of 350 flights. 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 14:00 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1353 runs 15 points better at 87.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1353 quarter by quarter

DL 1353 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.9% on time and its weakest Jan–Mar 2026 at 80.8%, a swing of 10 points on roughly 88 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 1353 did best on Wednesday at 98.0% on time and worst on Tuesday at 83.0%. Each day rests on about 50 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1353 runs late

One category carries most of the weight here. Carrier accounts for 53% of the 2,245 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, 53%, 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 1,181 of the 2,245 delay minutes reported here. The split is drawn from 2,245 delay minutes reported on DL 1353.

Cancellations sit at 2.00% against a national 1.81%, which is ordinary. Diversions add another 0.29%.

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 8.1% 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 526 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 1353 is not only a ATL to PIT flight. It also flew PIT to ATL (350 flights, 86.1% 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. 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.
