Other routes DL3099 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.

| HSV→ATL Huntsville to Atlanta | 2026-04-13 – 2026-05-06 | 24 | — |
| VPS→ATL Valparaiso to Atlanta | 2025-10-06 – 2025-12-02 | 58 | — |
Because the same number has served different journeys, the statistics above describe only the route DL3099 currently operates. Blending them would produce an average of two different flights.
Why DL3099 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
Share of the delay minutes US DOT attributed to each cause for DL3099 on ATL → AVL. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Data and methodology
Calculated by FlyerIntel from 402 records of DL3099 operating ATL → AVL, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
