Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1376, check with Delta Air Lines.

DL 1376 earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 19 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 357 flights, with a median arrival 14 minutes early.

Set against the rest of the country, DL 1376's record is 19 points better than the US average of 77.6%. That gap is worth roughly 190 fewer late arrivals for every thousand flights.

These figures cover 357 flights between July 2025 and June 2026. The median arrival is 14 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 1376 flies

DL 1376 is scheduled to leave West Palm Beach (PBI) at 06:00 local time and reach Atlanta (ATL) at 07:48. That slot held for 357 of the 357 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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 1376 runs 7 points better at 96.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 1376 next to PBI to ATL

Across the year

DL 1376 quarter by quarter

Quarter by quarter DL 1376 held fairly steady: 96.4% in Jul–Sep 2025, 96.7% in Oct–Dec 2025, 96.6% in Jan–Mar 2026 and 96.7% in Apr–Jun 2026. A spread of half a point is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1376 did best on Wednesday at 100.0% on time and worst on Monday at 86.3%. Each day rests on about 51 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1376 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 1,205 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
55%
Extreme weather
37%
National Airspace System
9%

Extreme weather accounts for 37% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 5.9 times the usual weather exposure. The split is drawn from 1,205 delay minutes reported on DL 1376.

Cancellations sit at 1.40% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.3% 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 545 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.

Every one of the 357 flights under DL 1376 in the data flew PBI 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. 357 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 1376

For a booking, DL 1376 has one of the better records a US domestic flight can show: 96.6% on time and 1.40% cancelled. That is a base rate, not a promise about any single day.
