DL 1375 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 363 flights, with a median arrival 7 minutes early.

Set against the rest of the country, DL 1375's record is 9 points better than the US average of 77.6%. That gap is worth roughly 86 fewer late arrivals for every thousand flights.

These figures cover 363 flights between July 2025 and June 2026. The median arrival is 7 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 1375 flies

DL 1375 flies ATL to SYR without a single fixed slot. Its most common scheduled departure was 09:00, used on 94 of 363 flights, with 08:55 (76 flights) and 08:57 (58 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 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1375 runs 2 points better at 86.2%. 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 1375 quarter by quarter

Quarter by quarter DL 1375 held fairly steady: 87.9% in Jul–Sep 2025, 82.8% in Oct–Dec 2025, 87.2% in Jan–Mar 2026 and 86.7% 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.

By weekday, DL 1375 ranged from 82.0% on Sunday to 92.2% on Wednesday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1375 runs late

One category carries most of the weight here. Carrier accounts for 53% of the 2,095 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
22%
National Airspace System

Extreme weather
3%

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 1,103 of the 2,095 delay minutes reported here. The split is drawn from 2,095 delay minutes reported on DL 1375.

Cancellations sit at 2.20% against a national 1.81%, which is ordinary. Diversions add another 0.28%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.8% 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 794 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 1375 is not only a ATL to SYR flight. It also flew SYR to ATL (363 flights, 83.1% 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. 363 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.
