| 17 August 2026 | 3 hours 21 minutes | Late-arriving aircraft |

Delay causes
Why B6 607 runs late
Late-arriving aircraft accounts for 44% of the 5,535 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 27%National Airspace System
- 27%Carrier
- 2%Extreme weather
- 0%Security
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,535 reported delay minutes here, that single category outweighs weather by 22 to one. The split is drawn from 5,535 delay minutes reported on B6 607.
Cancellations are rare at 0.62%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
11.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 2,173 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 324 flights under B6 607 in the data flew FLL to LAS. 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. 324 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.
