These figures cover 251 flights between September 2025 and August 2026. The median arrival is 14 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 3028 runs late

Late-arriving aircraft accounts for 42% of the 763 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
42%
National Airspace System
42%
Carrier
16%

42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 763 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 763 delay minutes reported on DL 3028.

Cancellations sit at 2.39% 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 1.6% 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.

The same number turns up on three other city pairs in the data, including CAE to ATL (91), ATL to CAE (91) and ATL to CHA (1), but none flew often enough under DL 3028 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. 251 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 3028

For a booking, read DL 3028 as 97.1% on time with 2.39% cancelled over 251 flights. Those are rates from the past twelve months, not a forecast for any particular day.
