|---|---|---|
| 12 December 2025 | 14 hours 41 minutes | Carrier |
| 6 July 2026 | 14 hours 1 minute | Carrier |

Delay causes
Why B6 98 runs late
Late-arriving aircraft accounts for 51% of the 8,418 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 46%Carrier
- 3%National Airspace System
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,418 reported delay minutes here, that single category outweighs weather by 51 to one. The split is drawn from 8,418 delay minutes reported on B6 98.
Cancellations run at 5.12%, against 1.89% nationally. That is about one flight in twenty 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
17.5% 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 1,626 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 254 flights under B6 98 in the data flew DEN to JFK. 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. 254 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 98
For a booking, the cancellation rate is the figure to plan around on B6 98: 5.12% of its 254 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
