These figures cover 344 flights between September 2025 and August 2026. The median arrival is 15 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.

The latest arrival of the period was on 27 June 2026, 9 hours 25 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across June, March, May, December and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 June 2026 | 9 hours 25 minutes | Extreme weather |
| 16 March 2026 | 4 hours 2 minutes | Late-arriving aircraft |
| 11 May 2026 | 3 hours 54 minutes | Carrier |

Delay causes
Why DL 3089 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,508 reported delay minutes.
- 39%Late-arriving aircraft
- 25%Extreme weather
- 18%Carrier
- 18%National Airspace System
Extreme weather accounts for 25% 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 4.2 times the usual weather exposure. The split is drawn from 2,508 delay minutes reported on DL 3089.
Cancellations sit at 1.16% 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 3.5% 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 GSP (238), but none flew often enough under DL 3089 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GSP to ATL only.
One caution: this is a thin sample. 344 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 3089
For a booking, DL 3089 has one of the better records a US domestic flight can show: 92.9% on time and 1.16% cancelled. That is a base rate, not a promise about any single day.
