Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on ORD to JFK lands a B−, about a point better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 633 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 830 at 77.5% on time.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on ORD to JFK from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
JetBlue against every carrier on ORD to JFK
JetBlue flew 633 of the 2,135 flights on ORD to JFK, about 30% of it. Its 78.2% on time is 6 points better than the route as a whole, which runs 72.5%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from Delta at 92.3% to Frontier at 59.8%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 77.5% of the time; American Airlines manages 60.5%. Sample sizes sit next to every figure, because a two-point gap across 541 flights means less than a ten-point one.

American Airlines cancels 5.2% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 39 points, against 17 points between the best and worst carrier.
- 5am–8am259 flights85.3%
- 8am–11am182 flights80.8%
- 11am–2pm89 flights77.9%
- 2pm–5pm21 flights—
- 5pm–8pm82 flights46.2%
- 8pm–5am—
Scale runs 40% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 46.2% on time, against 85.3% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 259 flights scheduled in it.
Across the year
JetBlue on ORD to JFK through the year
December is the weak month at 64.5% on time, against 92.2% in May. 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 93 flights.
Across the week, Wednesday is the strongest day at 80.2% on time and Saturday the weakest at 75.6%, a spread of 5 points.

The worst days
Worst days for JetBlue on ORD to JFK
The latest arrival of the period was on 31 August 2026, 19 hours 48 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across August, March, September and June, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 31 August 2026 | 19 hours 48 minutes | Carrier |
| 7 March 2026 | 10 hours 54 minutes | National Airspace System |
| 12 March 2026 | 9 hours 59 minutes | Late-arriving aircraft |
| 15 September 2025 | 9 hours 12 minutes | National Airspace System |

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 13,000 reported delay minutes.
- 41%Late-arriving aircraft
- 34%National Airspace System
- 24%Carrier
- 1%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 13,382 reported delay minutes.
34% 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 4,541 minutes out of 13,000, against a national NAS share of 21%.
Cancellations run at 7.90%, against 1.89% nationally. That is about one flight in twelve 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
11.0% 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 740 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 64.0% on time across 634 flights, 14 points below 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 14 points of difference.
One caution: this is a thin sample. 633 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 ORD to JFK
Put together: the delay figures matter less here than the 7.90% cancellation rate. A late arrival costs you close to two hours; 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. 582 completed flights over 12 months sit behind that.
