These figures cover 358 flights between September 2025 and August 2026. The median arrival is 12 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 7 July 2026, 7 hours 56 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 July 2026 | 7 hours 56 minutes | Carrier |
| 15 February 2026 | 2 hours 58 minutes | Carrier |
| 7 December 2025 | 2 hours 48 minutes | Carrier |

Delay causes
Why DL 2333 runs late
Carrier accounts for 65% of the 2,260 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Carrier
- 18%Late-arriving aircraft
- 16%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 65%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,468 of the 2,260 delay minutes reported here. The split is drawn from 2,260 delay minutes reported on DL 2333.
Cancellations run at 3.91%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.6% 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 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 2333 is not only a DTW to JAX flight. It also flew JAX to DTW (358 flights, 90.7% 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. 358 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.
