Historical statistics for July 2025 to June 2026, not live status. For today’s B6 97, check with JetBlue Airways.

B6 97 earns a D, which is as low as this site's scale goes for a reason. Only 57.9% of flights arrive inside the 15-minute window, 20 points worse than the national rate of 77.6%. Late arrivals average about an hour. Treat any tight connection here as a coin flip. That rests on 254 flights, with a median arrival 7 minutes late.

The national on-time rate over the same period is 77.6%, so B6 97 runs 20 points behind the country as a whole. Across a thousand flights that is about 197 extra late arrivals.

These figures cover 254 flights between July 2025 and June 2026. Beyond the headline rate, 15.4% 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 B6 97 flies

B6 97 flies JFK to DEN without a single fixed slot. Its most common scheduled departure was 20:18, used on 30 of 254 flights, with 20:12 (29 flights) and 20:14 (28 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 20:18 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and B6 97 runs 13 points worse at 57.9%. 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

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 Oct–Dec 2025 at 52.0%, a swing of 11 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.

Scale runs 45% to 70%. Rows with fewer than 30 flights show a dash.

By weekday, B6 97 did best on Wednesday at 73.3% on time and worst on Sunday at 42.1%. Each day rests on about 36 flights, so a gap of 31 points is worth noticing but could still narrow in another year.

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 6,163 reported delay minutes.

National Airspace System

Extreme weather

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,163 reported delay minutes here, that single category outweighs weather by 15 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,163 delay minutes reported on B6 97.

Cancellations run at 2.76%, against 1.81% nationally. That is roughly one flight in 40 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. 15.4% 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 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: 2.76% 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.
