What the record says about this route
The cancellation rate for the period is 2.57%, but almost all of it belongs to one month: January 2026, when 11.29% of flights on this route did not operate. Outside that month the route cancelled at around 1.46%. Whatever happened in January was an event, not the normal state of this route.
The season swings this route hard. In November it ran 30.4 points more punctual than in February — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
The shape of the lateness matters here. Flights on this route are not late often, but when they are late they are late by about 98 minutes — long enough to lose a connection or an evening. The on-time percentage looks reassuring and understates the consequence of being on the wrong flight.
This is a thin route — 544 flights across the whole period. On a route this infrequent a cancellation is far more costly than the rate suggests, because the next departure may not be the same day.
Which airline should you fly on this route?
Over January 2025 – August 2026, Delta Air Lines arrived on time most often on JFK to STT. American Airlines was late most often. Flights ran closest to schedule in September and worst in February.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on JFK to STT during January 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
