These figures cover 326 flights between September 2025 and August 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.

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 326 of the 326 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Across the year
DL 1376 quarter by quarter
Quarter by quarter DL 1376 held fairly steady: 96.7% in Oct–Dec 2025, 96.6% in Jan–Mar 2026, 96.7% in Apr–Jun 2026 and 100.0% in Jul–Sep 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Jan–Mar 202690 flights96.6%
- Apr–Jun 202691 flights96.7%

By weekday, DL 1376 did best on Wednesday at 100.0% on time and worst on Monday at 84.8%. Each day rests on about 47 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

|---|---|---|
| 16 March 2026 | 6 hours 13 minutes | Extreme weather |
| 26 January 2026 | 2 hours 56 minutes | Carrier |
| 7 May 2026 | 1 hour 51 minutes | Carrier |

Delay causes
Why DL 1376 runs late
Carrier accounts for 47% of the 1,040 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Carrier
- 43%Extreme weather
- 10%National Airspace System
Extreme weather accounts for 43% 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 7.1 times the usual weather exposure. The split is drawn from 1,040 delay minutes reported on DL 1376.
Cancellations sit at 1.53% against a national 1.89%, 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 2.2% land an hour or more behind schedule, against 8.3% 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.
Every one of the 326 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. 326 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, read DL 1376 as 96.9% on time with 1.53% cancelled over 326 flights. Those are rates from the past twelve months, not a forecast for any particular day.
