JetBlue on JFK to MSY lands a B−, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 415 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on JFK to MSY 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 JFK to MSY
JetBlue flew 415 of the 1,142 flights on JFK to MSY, about 36% of it. Its 76.3% on time is 3 points worse than the route as a whole, which runs 79.4%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 81.6% to Frontier at 28.6%. One 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.

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 30 points, against half a point between the best and worst carrier.

- 8am–11am196 flights78.0%

Book the early departure. Flights leaving between 5am–8am arrive on time 91.7% of the time, against 61.7% for the afternoon window. That is 30 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 196 flights scheduled in it.

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 6,874 reported delay minutes.
- 39%Late-arriving aircraft
- 26%Carrier
- 22%National Airspace System
- 13%Extreme weather
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 6,874 reported delay minutes.
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,874 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 5.30%, against 1.89% nationally. That is about 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 stage length
What a delay here costs
9.7% 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 1,182 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 72.2% on time across 415 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 415 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 MSY
Put together: the delay figures matter less here than the 5.30% cancellation rate. A late arrival costs you a little over 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. 393 completed flights over 12 months sit behind that.
