These figures cover 289 flights between September 2025 and August 2026. The median arrival is 5 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.

A 10:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 307 runs 8 points worse at 75.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 307 quarter by quarter
DL 307 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.4% on time and its weakest Oct–Dec 2025 at 66.0%, a swing of 16 points on roughly 72 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.

- Oct–Dec 202548 flights66.0%
- Jan–Mar 202672 flights66.7%
- Apr–Jun 202691 flights82.4%
- Jul–Sep 202662 flights76.7%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 307 did best on Wednesday at 85.3% on time and worst on Monday at 66.7%. Each day rests on about 41 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 307 runs when it is late
DL 307 often beats the schedule: 90 of 286 completed flights, 31%, arrived 15 minutes or more early. The 70 late arrivals split 26 under half an hour, 22 between 30 and 60 minutes, and 22 an hour or more.

Share of 286 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 48 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at HNL.
The worst days
Worst days for DL 307
The latest arrival of the period was on 22 January 2026, 7 hours 31 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 January 2026 | 7 hours 31 minutes | Carrier |
| 24 March 2026 | 5 hours 34 minutes | Carrier |
| 30 January 2026 | 5 hours 4 minutes | Carrier |

Delay causes
Why DL 307 runs late
Carrier accounts for 75% of the 6,010 delay minutes carriers reported here, and the remaining four split what is left.
- 75%Carrier
- 18%National Airspace System
- 4%Extreme weather
- 3%Late-arriving aircraft
The largest share of delay minutes, 75%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,483 of the 6,010 delay minutes reported here. The split is drawn from 6,010 delay minutes reported on DL 307.
Cancellations sit at 1.04% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.7% 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 an hour and a half, which a normal layover absorbs.
At 4,475 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on one other city pair in the data, including ATL to GSP (1), but none flew often enough under DL 307 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to HNL only.
One caution: this is a thin sample. 289 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.
What to do with this
