Across the year
B6 97 quarter by quarter
B6 97 did not run the same all year. Its best quarter was Apr–Jun 2026 at 63.3% on time and its weakest Jul–Sep 2026 at 39.2%, a swing of 24 points on roughly 64 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.

- Jan–Mar 202649 flights57.4%

By weekday, B6 97 did best on Tuesday at 66.7% on time and worst on Sunday at 37.8%. Each day rests on about 36 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Share of 240 completed flights by arrival against schedule.
22 of 109 late departures made up the time and arrived on time, 20% of them. In the other direction, 22 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 DEN.
The worst days
Worst days for B6 97
The latest arrival of the period was on 6 July 2026, 3 hours 35 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 July 2026 | 3 hours 35 minutes | Carrier |
| 12 March 2026 | 3 hours 25 minutes | Late-arriving aircraft |

Delay causes
Why B6 97 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 7,068 reported delay minutes.
- 36%Late-arriving aircraft
- 35%Carrier
- 26%National Airspace System
- 3%Extreme weather
- 0%Security
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,068 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 7,068 delay minutes reported on B6 97.
Cancellations run at 5.51%, against 1.89% nationally. That is roughly 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
19.6% 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 97 in the data flew JFK to DEN. 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 97
For a booking, the cancellation rate is the figure to plan around on B6 97: 5.51% of its 254 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
