These figures cover 303 flights between September 2025 and August 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.

By weekday, DL 3070 did best on Wednesday at 90.7% on time and worst on Sunday at 72.1%. Each day rests on about 43 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

| 7 September 2025 | 9 hours 5 minutes | Carrier |
| 18 June 2026 | 3 hours 32 minutes | Late-arriving aircraft |

Delay causes
Why DL 3070 runs late
Carrier accounts for 49% of the 3,531 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 42%Late-arriving aircraft
- 4%Extreme weather
- 4%National Airspace System
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,531 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 3,531 delay minutes reported on DL 3070.
Cancellations sit at 1.32% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.0% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
Every one of the 303 flights under DL 3070 in the data flew ATL to ILM. 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. 303 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 3070
For a booking, read DL 3070 as 80.6% on time with 1.32% cancelled over 303 flights. Those are rates from the past twelve months, not a forecast for any particular day.
