Historical statistics for July 2025 to June 2026, not live status. For today’s DL 753, check with Delta Air Lines.

DL 753 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 about 45 minutes. That rests on 334 flights, with a median arrival 6 minutes early.

Set against the rest of the country, DL 753's record is 7 points better than the US average of 77.6%. That gap is worth roughly 72 fewer late arrivals for every thousand flights.

These figures cover 334 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 753 flies

DL 753 flies ATL to LAX without a single fixed slot. Its most common scheduled departure was 14:43, used on 56 of 334 flights, with 14:41 (56 flights) and 14:55 (41 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 14:43 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 753 runs 12 points better at 84.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 753 quarter by quarter

Quarter by quarter DL 753 held fairly steady: 82.4% in Jul–Sep 2025, 83.7% in Oct–Dec 2025, 86.0% in Jan–Mar 2026 and 87.6% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202659 flights86.0%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 753 did best on Wednesday at 89.1% on time and worst on Monday at 77.1%. Each day rests on about 48 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 753 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 2,220 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.

Late-arriving aircraft
21%
National Airspace System
20%
Extreme weather
3%

The largest share of delay minutes, 56%, 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 1,246 of the 2,220 delay minutes reported here. The split is drawn from 2,220 delay minutes reported on DL 753.

Cancellations sit at 0.90% against a national 1.81%, which is ordinary. Diversions add another 0.60%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.6% 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.

At 1,947 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 334 flights under DL 753 in the data flew ATL to LAX. 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. 334 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 753

For a booking, read DL 753 as 84.8% on time with 0.90% cancelled over 334 flights. Those are rates from the past twelve months, not a forecast for any particular day.
