These figures cover 267 flights between September 2025 and August 2026. The median arrival is 10 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.

Across the year
DL 2994 quarter by quarter

The worst days
Worst days for DL 2994
The latest arrival of the period was on 9 November 2025, 3 hours 1 minute behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 3 hours 1 minute | Late-arriving aircraft |
| 9 March 2026 | 2 hours 28 minutes | Late-arriving aircraft |
| 24 August 2026 | 2 hours 10 minutes | Late-arriving aircraft |
| 31 March 2026 | 2 hours 8 minutes | Late-arriving aircraft |

Delay causes
Why DL 2994 runs late
Late-arriving aircraft accounts for 77% of the 2,589 delay minutes carriers reported here, and the remaining four split what is left.
- 77%Late-arriving aircraft
- 9%Extreme weather
- 9%National Airspace System
- 5%Carrier
77% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,589 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 2,589 delay minutes reported on DL 2994.
Cancellations are rare at 0.75%, 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
5.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 813 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
DL 2994 is not only a JAX to DTW flight. It also flew DTW to JAX (267 flights, 78.8% 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. 267 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.
