| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 December 2025 | 25 hours 56 minutes | National Airspace System |
| 19 July 2026 | 17 hours 51 minutes | Carrier |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 44% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 40%National Airspace System
- 16%Carrier
- 0%Extreme weather
44% 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 44 to one. The split is drawn from 14,136 reported delay minutes.
40% 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 5,642 minutes out of 14,000, against a national NAS share of 21%.
Cancellations run at 3.27%, against 1.89% nationally. That is about one flight in 30 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
11.6% 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 901 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 77.9% on time across 581 flights, 8 points above 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 8 points of difference.
One caution: this is a thin sample. 581 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 SAV to BOS
Put together: the delay figures matter less here than the 3.27% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 562 completed flights over 12 months sit behind that.
