These figures cover 260 flights between September 2025 and August 2026. The median arrival is 17 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.

| 7 March 2026 | 13 hours 19 minutes | Carrier |

Delay causes
Why DL 3020 runs late
Carrier accounts for 77% of the 1,847 delay minutes carriers reported here, and the remaining four split what is left.
- 77%Carrier
- 17%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,428 of the 1,847 delay minutes reported here. The split is drawn from 1,847 delay minutes reported on DL 3020.
Cancellations run at 2.69%, against 1.89% nationally. That is about one flight in 40 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 3.6% 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.
Every one of the 260 flights under DL 3020 in the data flew HSV 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. 260 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 3020
For a booking, the cancellation rate is the figure to plan around on DL 3020: 2.69% of its 260 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.
