How DL307 performs
606 operations, September 2024 – August 2026.
Between its first and last recorded date on DTW → HNL, DL307 averaged about 6 operations a week (606 in 720 days, cancelled ones included).
DL307 arrived on time 81.5% of the time, level with the 81.7% for all DTW → HNL flights: on arrival punctuality it is a typical departure on this route, neither better nor worse.
DL307’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 10:00 AM earlier on, and around 10:30 AM more recently — a 30-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

Why DL307 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies DL307 comes in late, and what that does to the departure.
The aircraft flying DL307 came in 15 or more minutes late on 18% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Matched by tail number to the aircraft’s previous flight into DTW: 420 of 604 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| DL307 | 18% |
| Network, same turn | 33% |
A long gap on the ground gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 3 to 6 hours. How often DL307’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves DTW late, does that still matter by the time it reaches HNL?
DL307 pushes back an average of 12.9 minutes late and reaches the gate at HNL an average of 4.9 minutes late. The 8.0 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. Its 19.1 minutes on the taxiways at DTW is about what any departure from the airport in that hour spends.
On arrival at HNL, DL307 spends 7.9 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at HNL spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 41,452 DTW departures. Taxi-in is landing to gate, set against 191,221 arrivals at HNL. More on taxi time.

The hour it leaves DTW
DL307 has one departure time, 10:00 AM, so this is what that hour at DTW is worth.
On-time arrival rate. 41,452 departures from DTW are scheduled in the 10 AM–11 AM hour over the period, against 398,799 across the whole day.
DL307 is scheduled out of DTW at 10:00 AM, in the 10 AM–11 AM bank. Departures from DTW in that hour arrive on time 83.6% of the time against 79.6% across the airport’s whole day — the slot alone is worth 4.0 points better before anything about this particular flight is considered.
Both airport figures cover every destination from DTW, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

Data and methodology
Calculated by FlyerIntel from 606 records of DL307 operating DTW → HNL, 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 reported separately, not in the on-time rate.
