These figures cover 348 flights between July 2025 and June 2026. Beyond the headline rate, 9.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When DL 707 flies
DL 707 flies JFK to LAX without a single fixed slot. Its most common scheduled departure was 19:45, used on 114 of 348 flights, with 19:00 (60 flights) and 19:25 (53 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 19:0060 flights17.2%
- Departs 19:2553 flights15.2%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 19:45 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 707 runs 6 points better at 74.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 707 quarter by quarter
Quarter by quarter DL 707 held fairly steady: 76.4% in Jul–Sep 2025, 72.3% in Oct–Dec 2025, 75.6% in Jan–Mar 2026 and 71.8% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights76.4%
- Oct–Dec 202586 flights72.3%
- Jan–Mar 202689 flights75.6%
- Apr–Jun 202681 flights71.8%
Scale runs 65% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, DL 707 did best on Friday at 81.6% on time and worst on Sunday at 64.0%. Each day rests on about 50 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 707 runs late
One category carries most of the weight here. Carrier accounts for 55% of the 6,334 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 55%Carrier
- 32%National Airspace System
- 12%Late-arriving aircraft
- 1%Extreme weather
- 0%Security
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,471 of the 6,334 delay minutes reported here. The split is drawn from 6,334 delay minutes reported on DL 707.
Cancellations run at 3.45%, against 1.81% nationally. That is about one flight in 30 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
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.
Every one of the 348 flights under DL 707 in the data flew JFK to LAX. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 348 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
Booking DL 707
For a booking, the cancellation rate is the figure to plan around on DL 707: 3.45% of its 348 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
