These figures cover 287 flights between September 2025 and August 2026. The median arrival is 16 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.

Delay causes
Why DL 3052 runs late
Late-arriving aircraft accounts for 82% of the 1,950 delay minutes carriers reported here, and the remaining four split what is left.
- 82%Late-arriving aircraft
- 11%Carrier
- 7%National Airspace System
82% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,950 reported delay minutes here, that single category outweighs weather by 82 to one. The split is drawn from 1,950 delay minutes reported on DL 3052.
Cancellations sit at 2.09% 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 4.3% 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 GSO (194), but none flew often enough under DL 3052 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GSO to ATL only.
One caution: this is a thin sample. 287 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 3052
For a booking, read DL 3052 as 90.0% on time with 2.09% cancelled over 287 flights. Those are rates from the past twelve months, not a forecast for any particular day.
