DL 570 earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 365 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 570's record is 16 points better than the US average of 77.6%. That gap is worth roughly 155 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 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.

Schedule

When DL 570 flies

DL 570 flies SFO to ATL without a single fixed slot. Its most common scheduled departure was 06:00, used on 210 of 365 flights, with 06:15 (97 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 570 runs 4 points better at 93.1%. 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 570 quarter by quarter

Quarter by quarter DL 570 held fairly steady: 95.6% in Jul–Sep 2025, 92.2% in Oct–Dec 2025, 94.3% in Jan–Mar 2026 and 90.1% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights95.6%
Oct–Dec 202592 flights92.2%
Jan–Mar 202690 flights94.3%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 570 ranged from 88.2% on Tuesday to 96.2% on Wednesday. With about 52 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 570 runs late

One category carries most of the weight here. Carrier accounts for 64% of the 2,863 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
64%
Late-arriving aircraft
29%
National Airspace System
7%

The largest share of delay minutes, 64%, 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 1,834 of the 2,863 delay minutes reported here. The split is drawn from 2,863 delay minutes reported on DL 570.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

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 2,139 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 365 flights under DL 570 in the data flew SFO to ATL. 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. 365 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 570

For a booking, DL 570 has one of the better records a US domestic flight can show: 93.1% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
