BEST VALUE
Heavy
The Gulfstream G450 clears both runways and has range headroom on the 3,643 nm leg without stepping up into a larger, more expensive cabin — the lowest hourly cost that still handles this pair reliably.
Indicative all-in €68,700
FASTEST
Ultra Long Range
On 3,643 nm the Bombardier Global 5000 carries the highest cruise speed in the eligible short-list. The saving is roughly 21 minutes of block time against the smallest eligible class — worth it on a same-day return, marginal otherwise.
Indicative all-in €64,400

On Seattle → St Lucia, aircraft positioning is the biggest lever on price today.
PRICE DRIVERS
Aircraft based off-route are repositioned to Seattle before pickup — the shorter that leg, the more competitive the quote.
If the aircraft can't pick up a return charter from St Lucia, the empty repositioning leg is baked into your quote.
Landing, handling and ramp fees on BFI–UVF are set field by field — BFI and UVF each carry their own coordinated-airport surcharge profile.
On a 3,643 nm sector, jet-fuel price movements meaningfully change the quote — operators quote against a live fuel-uplift band.
Seattle → St Lucia demand cycles pull the 3,643 nm sector off its low band on peak weeks.
Ramp capacity at UVF constrains the lift available for 3,643 nm inbounds from Seattle — operators quote accordingly.
Weather rarely re-prices BFI–UVF beyond marginal fuel adjustments over 3,643 nm.
Slot coordination at UVF — peak-season Saturdays especially — forces earlier commitment on Seattle departures and raises handling on BFI–UVF.
Ultra-long sectors trigger augmented crew requirements — an extra pilot's cost is reflected in the hourly rate.
Overnight parking at UVF is normally available and adds a defined ramp and handling fee to the BFI–UVF quote.
SAVING OPPORTUNITIES
Saving levers on Seattle → St Lucia
If the aircraft is already positioned closer to another Seattle-area field, using it reduces positioning cost and often trims 5–15% off the quote.
Alternative arrivals near UVF can trim handling and slot pressure on BFI–UVF — see the airport comparison above.
BFI ↔ UVF (3,643 nm) is a corridor we monitor for empty legs — set an alert and match one when your dates flex.
Departing 2–4 hours off the peak slot window at BFI drops handling and slot fees on the 3,643 nm run to UVF.
A same-aircraft return on BFI–UVF avoids the repositioning charge back to base — say so in the quote request.

Seattle → St Lucia operational profile
Nonstop feasibility
Nonstop for heavy jets (Falcon 8X, Challenger 605/650 with light payload); a full cabin may want a Global 6000.
Typical flight level
FL410–FL450 over the 3,643 nm BFI–UVF sector
Typical routing
Overland European upper routes — direct via UN airways with minimal detour.
Runway
9,003 ft (shorter of BFI and UVF) clears heavy metal unrestricted.
Fuel stop likelihood
No fuel stop on 3,643 nm; BFI–UVF is a single-sector mission for every class we quote.
Cabin service
Multi-course dining, sleep configuration and hot cabin service — full FA experience.
Best departure time
Mid-morning (10:00–12:00) departure from BFI clears the weekday slot peak and lands UVF before midday handling pressure.

€55,000 – €70,400
Ultra Long Range through Heavy over 3,643 nm BFI–UVF, all-in of landing, handling, crew and fuel surcharge. Weekend and peak-season departures out of BFI sit at the upper end.
Price stand: August 2026. BFI–UVF quotes move with fuel, crew duty and slot availability — we re-price at the point of booking.
BFI–UVF supply — thin
BFI — 20 archived movements (10 out / 10 in) from 8 operators. UVF — 1 archived movements (0 out / 1 in) from 1 operators. Most BFI–UVF lift positions in, so expect a ferry element in the price and give us 48h+ where you can.
Positioning into Seattle (BFI)
When the based fleet is committed, the next BFI–UVF lift comes from KBFI (0 nm, 4 aircraft), KSEA (5 nm, 2 aircraft), KOKH (46 nm, 1 aircraft). Those ferries add roughly 20–45 minutes of billed time, which is why identical requests can quote differently on the same day.
Positioning into St Lucia (UVF)
With little metal based on the field, aircraft typically ferry in from SVMG (245 nm, 1 aircraft). A 30–60 minute positioning sector is normal and is already inside the quotes above — beware anyone showing a price that ignores it.
Phenom 100 / Citation M2 and comparable light jets
At 3,643 nm this sector is beyond a comfortable light-jet leg with full seats and bags — you buy a fuel stop, and a stop costs more than the class saves. It is also the class where golf bags and ski gear stop fitting.
Empty Legs
Repositioning legs departing BFI within 14 days, priced per aircraft for up to 19 seats.

LEAD TIME
48–72 hours is comfortable — 12 hours is achievable when aircraft are in position.
BEST BOOKING WINDOW
Tuesday–Thursday midweek is typically the lowest-friction window on this pair.
FLEXIBLE DATES
A ±1-day window opens up meaningfully more empty-leg and repositioning options — worth signalling in the enquiry.
