These figures cover 255 flights between September 2025 and August 2026. The median arrival is 12 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 3154 quarter by quarter
Quarter by quarter DL 3154 held fairly steady: 90.8% in Jan–Mar 2026, 97.7% in Apr–Jun 2026 and 95.1% in Jul–Sep 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 3154 ranged from 88.9% on Tuesday to 100.0% on Saturday. With about 36 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

The worst days
Worst days for DL 3154
The latest arrival of the period was on 12 May 2026, 5 hours 56 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

|---|---|---|
| 12 May 2026 | 5 hours 56 minutes | Carrier |
| 16 March 2026 | 4 hours 48 minutes | Carrier |

Delay causes
Why DL 3154 runs late
Carrier accounts for 62% of the 2,146 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 26%Extreme weather
- 12%National Airspace System
Extreme weather accounts for 26% 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 4.4 times the usual weather exposure. The split is drawn from 2,146 delay minutes reported on DL 3154.
Cancellations run at 3.14%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.5% 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 same number turns up on one other city pair in the data, including ATL to AGS (1), but none flew often enough under DL 3154 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DAB to ATL only.
One caution: this is a thin sample. 255 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 3154
For a booking, the cancellation rate is the figure to plan around on DL 3154: 3.14% of its 255 scheduled flights did not operate. A late arrival costs about 2.2 hours, but a cancellation costs the day, so leave a later option open.
