These figures cover 348 flights between September 2025 and August 2026. The median arrival is 8 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 07:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 223 runs 10 points worse at 79.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

- Jan–Mar 202685 flights77.5%

By weekday, B6 223 did best on Thursday at 84.6% on time and worst on Sunday at 67.3%. Each day rests on about 50 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Arrival by arrival

B6 223 often beats the schedule: 130 of 337 completed flights, 39%, arrived 15 minutes or more early. The 69 late arrivals split 33 under half an hour, 17 between 30 and 60 minutes, and 19 an hour or more.

Share of 337 completed flights by arrival against schedule.
10 of 40 late departures made up the time and arrived on time, 25% of them. In the other direction, 39 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 B6 223
The latest arrival of the period was on 5 January 2026, 4 hours 38 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across January, October, September, July and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 January 2026 | 4 hours 38 minutes | Late-arriving aircraft |
| 14 October 2025 | 3 hours 55 minutes | National Airspace System |
| 10 September 2025 | 3 hours 38 minutes | Carrier |
| 8 July 2026 | 3 hours 18 minutes | Late-arriving aircraft |

Delay causes
Why B6 223 runs late
National Airspace System accounts for 51% of the 3,689 delay minutes carriers reported here, and the remaining four split what is left.

- 23%Late-arriving aircraft
- 21%Carrier
- 3%Extreme weather
- 1%Security
51% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,888 minutes out of 3,689, against a national NAS share of 21%. The split is drawn from 3,689 delay minutes reported on B6 223.
Cancellations run at 2.87%, against 1.89% nationally. That is roughly 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
5.6% 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 roughly 55 minutes, which a normal layover absorbs.
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 B6 223 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 B6 223
For a booking, the cancellation rate is the figure to plan around on B6 223: 2.87% of its 348 scheduled flights did not operate. A late arrival costs roughly 55 minutes, but a cancellation costs the day, so leave a later option open.
