DL 767 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.3%.

These figures cover 341 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 767 quarter by quarter
DL 767 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.3% on time and its weakest Jul–Sep 2026 at 73.8%, a swing of 20 points on roughly 68 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 202580 flights80.8%

Scale runs 65% to 100%.
By weekday, DL 767 did best on Friday at 89.8% on time and worst on Monday at 77.1%. Each day rests on about 49 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 767 runs when it is late
DL 767 often beats the schedule: 130 of 333 completed flights, 39%, arrived 15 minutes or more early. The 52 late arrivals split 25 under half an hour, 15 between 30 and 60 minutes, and 12 an hour or more.

Share of 333 completed flights by arrival against schedule.
7 of 30 late departures made up the time and arrived on time, 23% of them. In the other direction, 29 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 LAX.
The worst days
Worst days for DL 767
The latest arrival of the period was on 25 June 2026, 5 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.

Delay causes
Why DL 767 runs late
Carrier accounts for 55% of the 2,985 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 37%National Airspace System
- 4%Extreme weather
- 2%Security
- 1%Late-arriving aircraft
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,648 of the 2,985 delay minutes reported here. The split is drawn from 2,985 delay minutes reported on DL 767.
Cancellations sit at 1.76% against a national 1.89%, which is ordinary. Diversions add another 0.59%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.6% 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.
At 2,475 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 two other city pairs in the data, including ATL to BTR (13) and BTR to ATL (13), but none flew often enough under DL 767 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to LAX only.
One caution: this is a thin sample. 341 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
