Across the year
DL 2990 quarter by quarter
DL 2990 did not run the same all year. Its best quarter was Jan–Mar 2026 at 83.3% on time and its weakest Jul–Sep 2026 at 59.0%, a swing of 24 points on roughly 85 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 2990 did best on Tuesday at 86.1% on time and worst on Sunday at 66.7%. Each day rests on about 36 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

The latest arrival of the period was on 21 May 2026, 9 hours 17 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 May 2026 | 9 hours 17 minutes | Carrier |
| 21 August 2026 | 7 hours 48 minutes | Carrier |
| 19 July 2026 | 5 hours 41 minutes | Late-arriving aircraft |

Delay causes
Why DL 2990 runs late
Late-arriving aircraft accounts for 54% of the 5,733 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 24%Carrier
- 13%National Airspace System
- 8%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,733 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 5,733 delay minutes reported on DL 2990.
Cancellations are rare at 0.78%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
10.7% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
DL 2990 is not only a JAX to ATL flight. It also flew ATL to JAX (255 flights, 77.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 255 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.
