Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on BOS to SAV lands a B, level with the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 581 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on BOS to SAV from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 581 flights between September 2025 and August 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
JetBlue against every carrier on BOS to SAV
JetBlue flew 581 of the 1,023 flights on BOS to SAV, most of the route. Its 77.9% on time is 2 points worse than the route as a whole, which runs 79.4%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Delta at 87.5% to JetBlue at 77.9%. 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 34 points, against half a point between the best and worst carrier.
- 5am–8am150 flights88.7%
- 8am–11am199 flights78.2%
- 11am–2pm48 flights74.5%
- 2pm–5pm108 flights76.6%
- 5pm–8pm58 flights54.5%
- 8pm–5am18 flights—
Scale runs 45% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 54.5% on time, against 88.7% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 199 flights scheduled in it.
Across the year
JetBlue on BOS to SAV through the year
December is the weak month at 54.8% on time, against 88.2% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. April was the busiest month here, with 68 flights.
Across the week, Wednesday is the strongest day at 88.2% on time and Sunday the weakest at 67.7%, a spread of 21 points.
Arrival by arrival
How late JetBlue on BOS to SAV runs when it is late

Share of 562 completed flights by arrival against schedule.
21 of 110 late departures made up the time and arrived on time, 19% of them. In the other direction, 35 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SAV.
The worst days
Worst days for JetBlue on BOS to SAV
The latest arrival of the period was on 6 March 2026, 6 hours 12 minutes behind schedule; most of its delay minutes were filed as extreme weather. On three of the five worst days the largest share was filed as a late-arriving aircraft.

| 19 July 2026 | 5 hours 30 minutes | Late-arriving aircraft |

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 8,124 reported delay minutes.
- 38%Carrier
- 32%Late-arriving aircraft
- 24%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,095 of the 8,124 delay minutes reported here. The split is drawn from 8,124 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 88.7% on time here.
Cancellations run at 2.93%, against 1.89% nationally. That is roughly 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
7.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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 70.1% on time across 581 flights, 8 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 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 BOS to SAV
Put together: the delay figures matter less here than the 2.93% cancellation rate. A late arrival costs you about 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. 562 completed flights over 12 months sit behind that.
