Carrier by carrier
JetBlue against every carrier on CHS to JFK
JetBlue flew 637 of the 789 flights on CHS to JFK, most of the route. Its 72.5% on time is about level with the route as a whole at 73.5%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Delta at 100.0% to JetBlue at 72.5%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

The worst days
Worst days for JetBlue on CHS to JFK
The latest arrival of the period was on 6 August 2026, 15 hours 49 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 August 2026 | 15 hours 49 minutes | Carrier |
| 19 December 2025 | 15 hours 11 minutes | Carrier |
| 11 May 2026 | 8 hours 22 minutes | Carrier |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 50% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 31%Carrier
- 18%National Airspace System
- 0%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 14,281 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 85.7% on time here.
Cancellations run at 5.81%, against 1.89% nationally. That is roughly 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
12.0% 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 636 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 runs 72.8% on time across 638 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 637 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 CHS to JFK
Put together: the delay figures matter less here than the 5.81% cancellation rate. A late arrival costs you an hour and a half; 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. 599 completed flights over 12 months sit behind that.
