Departure window
When JetBlue runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against half a point between the best and worst carrier.
- 5am–8am82 flights87.5%
- 8am–11am206 flights71.5%
- 11am–2pm56 flights85.7%
- 2pm–5pm109 flights56.2%
- 5pm–8pm31 flights—
- 8pm–5am63 flights59.7%
Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 87.5% of the time, against 56.2% for the afternoon window. That is 31 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 206 flights scheduled in it.
Across the year
JetBlue on JFK to BNA through the year
December is the weak month at 53.5% on time, against 90.3% in March. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 62 flights.
Across the week, Tuesday is the strongest day at 78.3% on time and Thursday the weakest at 62.0%, a spread of 16 points.

Share of 507 completed flights by arrival against schedule.
17 of 122 late departures made up the time and arrived on time, 14% of them. In the other direction, 43 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 BNA.
The worst days
Worst days for JetBlue on JFK to BNA
The latest arrival of the period was on 18 March 2026, 5 hours 30 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 |
|---|---|---|
| 18 March 2026 | 5 hours 30 minutes | Carrier |
| 9 November 2025 | 4 hours 52 minutes | Carrier |
| 27 August 2026 | 4 hours 19 minutes | National Airspace System |
| 29 December 2025 | 3 hours 20 minutes | Late-arriving aircraft |
| 25 August 2026 | 3 hours 6 minutes | Carrier |
Delay causes
Why JetBlue runs late on this route
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 9,415 reported delay minutes.
- 36%Carrier
- 32%National Airspace System
- 30%Late-arriving aircraft
- 1%Extreme weather
- 0%Security
32% 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 3,059 minutes out of 9,415, against a national NAS share of 21%. The split is drawn from 9,415 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,395 of the 9,415 delay minutes reported here.
Cancellations run at 6.95%, against 1.89% nationally. That is about one flight in fifteen 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 stage length
What a delay here costs
12.8% 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.
The 765 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 73.8% on time across 549 flights, 3 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 3 points of difference.
One caution: this is a thin sample. 547 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 JetBlue on JFK to BNA
Put together: the delay figures matter less here than the 6.95% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 507 completed flights over 12 months sit behind that.
