B6BOS→MSY

JetBlue flew 479 of the 863 flights on BOS to MSY, most of the route. Its 72.0% on time is 4 points worse than the route as a whole, which runs 76.4%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Delta at 82.7% to American at 50.0%. 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.

JetBlue on BOS to MSY often beats the schedule: 179 of 471 completed flights, 38%, arrived 15 minutes or more early. The 132 late arrivals split 42 under half an hour, 41 between 30 and 60 minutes, and 49 an hour or more.

The latest arrival of the period was on 20 February 2026, 22 hours 42 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. On three of the five worst days the largest share was filed as a late-arriving aircraft.

10.4% 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 1,367 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 61.2% on time across 479 flights, 11 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 11 points of difference.

One caution: this is a thin sample. 479 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.
