The leg
Nantucket to St Barths
Measured airport to airport, ACK to SBH is 1,450 nautical miles. A light jet does it nonstop in something close to 3h 32m once taxi, climb and descent are counted.
This is where aircraft class starts to matter to your day, not just your comfort. A light jet may need a fuel stop that a super midsize does not, and a stop costs forty five minutes to an hour on the ground plus the fuel to climb back to altitude. The clock change is 1 hour ahead in winter and no clock change in summer, because the two cities shift their daylight saving rules on different dates.
You do not need a large cabin for the distance. A Learjet 45XR in the light jet class covers it nonstop with margin left over. A further 5 aircraft can do it nonstop on a good day, and those are the quotes worth reading carefully. A marginal leg becomes a fuel stop the moment the winds turn, the cabin fills, or the departure field is hot and high. 2 of the aircraft we track cannot make it without stopping at all, which does not rule them out. A stop on a cheaper airframe sometimes still wins on total cost, and the bid comparison will show you whether it does.
Book range figures assume long range cruise, standard reserves and a stated payload. Load the cabin, add bags, put the departure field at elevation on a hot afternoon, and the real number comes down. We treat anything above roughly 80 percent of book range as a leg that needs the operator to confirm against the specific tail number rather than the brochure.

Airports
Which runway you actually use
Departing Nantucket. Most charter traffic uses Nantucket Memorial (KACK / ACK). The credible alternates are Martha s Vineyard (MVY) and Barnstable Hyannis (HYA). Which one you leave from is worth deciding on ground time rather than on the map, because twenty minutes of extra driving often buys a cheaper ramp and a faster departure.
Summer weekend parking on Nantucket is limited and aircraft are often repositioned off island between legs. Coastal fog is a routine cause of delay from late spring through midsummer.
Arriving St Barths. Most charter traffic uses Gustaf III (TFFJ / SBH). The credible alternates are Princess Juliana Sint Maarten (SXM). Pick the one closest to where you are actually going. The airport with the famous name is frequently the wrong answer.
Gustaf III has a runway of roughly 2,100 ft with a steep approach over a hillside and requires a specific pilot qualification. Jets cannot land there. Standard practice is a jet into Sint Maarten followed by a short turboprop or helicopter transfer.
Runway length, ramp space and operating hours at the arrival field decide the aircraft as often as range does. Have the operator confirm all three against the tail number they are offering.
| Airport | ICAO | IATA | Metro | End | Role |
|---|---|---|---|---|---|
| Nantucket Memorial | KACK | ACK | Nantucket | Departure | Preferred |
| Martha s Vineyard | KMVY | MVY | Nantucket | Departure | Alternate |
| Barnstable Hyannis | KHYA | HYA | Nantucket | Departure | Alternate |
| Gustaf III | TFFJ | SBH | St Barths | Arrival | Preferred |
| Princess Juliana Sint Maarten | TNCM | SXM | St Barths | Arrival | Alternate |
Cost
What moves the number
We do not publish a price for this route, and neither should anyone else. Here is what the number is actually made of.
- Positioning. Where the aircraft sits when you call. If it is already on your departure ramp you pay for your legs only. If it has to fly in empty and fly home afterwards, someone pays for that, and it is you.
- Daily minimum. Most operators bill a minimum number of flight hours per day the aircraft is away. A short leg with a three night stay can price higher than a long leg that returns the same day.
- Crew duty. A crew has a legal duty limit. Cross enough time zones or depart late enough and the trip needs a second crew or an overnight, and both cost money.
- Ramp and handling. Landing fees, ramp fees, overnight parking and the FBO handling charge vary enormously between fields in the same metro.
- Peak days. Operators apply surcharges around the predictable weekends. Thanksgiving Sunday, the Super Bowl, Art Basel, the Fourth of July and the ski season change of week all price differently.
- Fuel and stops. A technical stop costs fuel to climb back to altitude, a landing fee, handling, and forty five minutes to an hour of ground time.
- De-icing. Winter departures from northern fields add de-icing, which is charged by volume of fluid and can be a serious number on a large aircraft.
- International handling. Customs, immigration, overflight permits, landing permits and a local handling agent. On some routings the permits need days of lead time.
Our fee sits on top of the operator price as its own line, visible, so you can see both halves. Send the trip and the operators bid against each other on all of the above at once.
Timing
Season, weather and the clock
St Barths sits in the tropics, where the practical seasons are wet and dry rather than hot and cold. Afternoon convective weather is the routine cause of delay, so morning departures hold their schedule more reliably.
Atlantic hurricane season runs June through November. It rarely cancels a trip outright, but it does move departure windows, and travel insurance is worth reading properly rather than skimming.
Questions
ACK to SBH
How long is a private jet flight from Nantucket to St Barths?
The great circle distance is 1,450 nautical miles, which is about 2,686 km. A light jet covers it nonstop in roughly 3h 32m block to block. A heavy jet flies the distance in about 3h 27m, and a light jet in about 3h 32m if it can make it without stopping. These are planning estimates in still air and exclude winds and air traffic routing.
Can a light jet fly Nantucket to St Barths nonstop?
Yes. A Embraer Phenom 300E covers this leg nonstop with comfortable margin, using about 74 percent of its published range. That is inside the band where a full cabin and average winds will not force a stop.
Which airport should I use in St Barths?
Gustaf III (TFFJ) handles most charter traffic. The alternates are Princess Juliana Sint Maarten (SXM). Choose on ground time to your final address rather than on the name you recognise. Gustaf III has a runway of roughly 2,100 ft with a steep approach over a hillside and requires a specific pilot qualification. Jets cannot land there.
Do I clear customs on a private flight from Nantucket to St Barths?
Yes. Crossing a border on a private aircraft still means customs and immigration at both ends, but it happens at the private terminal rather than in a terminal queue, and it is usually a matter of minutes. The operator files the passenger manifest in advance, so passport details are needed before departure rather than at the airport. Some routings also need landing or overflight permits with days of lead time, which is worth raising early.
What does a private jet from Nantucket to St Barths cost?
We do not publish a figure, because a fixed number for this route would be invented. The dominant variable is where the aircraft is parked when you call, not the aircraft type. Positioning legs, daily minimums, crew duty, ramp fees, peak day surcharges and taxes all move the total. Send the trip through the quote form and certificated operators bid against each other on it, sealed, without knowing who you are.
Are empty legs available on this route?
Sometimes. An empty leg exists when an operator has to reposition an aircraft along this track anyway, so the timing is theirs and not yours. They appear and vanish with little notice and get cancelled when the paying trip behind them changes. Flag empty legs on the quote form and we will include any that fit your window, but do not build a fixed commitment around one.
