London is the busiest transatlantic private-aviation corridor in Europe — City-of-London finance, family offices in Mayfair and Kensington, and Farnborough's Mach-0.90 permissions make it the default eastbound terminus. From Seattle, Bellevue tech leadership, Boeing executive traffic and Pacific-Northwest family offices sit behind BFI's transatlantic missions — block time on the 9h 51m sector runs on Boeing BBJ · ACJ319. Block time out of the West Coast typically runs 10–11 hours eastbound and 11–12 hours westbound depending on jet-stream position. Boeing Field (BFI) is closer to downtown than SeaTac and runs every Seattle private movement. Farnborough is the west London default — 45 minutes to Mayfair by chauffeur, 12 minutes by helicopter to Battersea. At 7,741 km the sector sits at the top of the heavy-jet envelope — direct eastbound in tailwind months, tech-stop at Goose Bay or Keflavík westbound on the Falcon 7X and Global 6000.

WHAT TO DO NEXT · AIRCRAFT CHOICE DECIDES THIS SECTOR
Aircraft choice matters more than usual here because the limiting field removes classes that otherwise have the range for the sector — the runway, not the distance, sets the short-list.
A second airport with comparable verified data serves at least one end of this pair, so the runway constraint can also be answered by changing the field rather than the aircraft.

BFI · Seattle

Arrival field
BQH · London
5,925ft
BFI publishes 10,007 ft of runway, which accepts ultra-long-range aircraft and below at full performance.
BQH publishes 5,925 ft, accepting midsize aircraft and below.
The 4,173 nm sector is inside the usable range of heavy jet and ultra-long-range metal after IFR reserves.
Runway length at BQH (London) — not range — removes heavy jet and ultra-long-range from this pair; Midsize is the practical ceiling into the field.
No class clears both fields nonstop at published performance — this pair is flown with a fuel stop or a runway-appropriate alternate.
ROUTE INTELLIGENCE · PRICING INTELLIGENCE
On Seattle → London, 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 London, the empty repositioning leg is baked into your quote.
Landing, handling and ramp fees on BFI–FAB are set field by field — BFI and FAB each carry their own coordinated-airport surcharge profile.
On a 4,173 nm sector, jet-fuel price movements meaningfully change the quote — operators quote against a live fuel-uplift band.
Seattle → London demand cycles pull the 4,173 nm sector off its low band on peak weeks.
Ramp capacity at FAB constrains the lift available for 4,173 nm inbounds from Seattle — operators quote accordingly.
Weather rarely re-prices BFI–FAB beyond marginal fuel adjustments over 4,173 nm.
Slot coordination at FAB — peak-season Saturdays especially — forces earlier commitment on Seattle departures and raises handling on BFI–FAB.
Ultra-long sectors trigger augmented crew requirements — an extra pilot's cost is reflected in the hourly rate.
Overnight parking at FAB is normally available and adds a defined ramp and handling fee to the BFI–FAB quote.
SAVING OPPORTUNITIES
Saving levers on Seattle → London
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 FAB can trim handling and slot pressure on BFI–FAB — see the airport comparison above.
BFI ↔ FAB (4,173 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 4,173 nm run to FAB.
A same-aircraft return on BFI–FAB avoids the repositioning charge back to base — say so in the quote request.

Phenom 100 / Citation M2 and comparable light jets
At 4,173 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.

Seattle → London frequently asked questions
ASK A QUESTIONThe great-circle sector is 4,173 nm. Published runway length at BQH (5,925 ft) removes heavy jet and ultra-long-range from this pair, so a nonstop time is only quotable once the operating field and aircraft are fixed.
Over the 4,173 nm sector our desk models midsize charter from €35,100 one-way with one planned technical fuel stop and super-midsize from €39,400 with one planned technical fuel stop. No modelled cabin category covers 4,173 nm nonstop after IFR reserves, so every row above assumes one planned technical fuel stop. light jet aircraft cannot cover the 4,173 nm nonstop after IFR reserves, which is why the modelled ladder opens at midsize rather than a smaller cabin. The two accepted categories sit close together on this sector, so moving up from midsize to super-midsize changes cabin and range headroom more than it changes the modelled figure. super-midsize aircraft operate into BQH under the published performance limit rather than at full runway performance, which is a payload and fuel planning point rather than a separate price. More than one field serves this pair, and the modelled rows above are the ones our desk applies to the primary airport pairing. These are modelled charter estimates for this pair — not live quotes, not observed transactions — and the final figure moves with aircraft positioning and availability on the date.
Embraer Praetor 600 (Super Midsize) is our standing pick — On 4,173 nm the Embraer Praetor 600 operates Seattle–London with one planned technical fuel stop — the operator files the stop based on payload, winds and ATC routing, and passengers normally stay on board.
BQH is closest at 45 min transfer. No coordination required
Nonstop for heavy jets (Falcon 8X, Challenger 605/650 with light payload); a full cabin may want a Global 6000.
Embraer Praetor 600 and larger types offer a full flat-bed configuration — the standard choice on this pair.
Westbound legs run longer against the prevailing jetstream — plan for the eastbound to be materially quicker.
10–14 days is comfortable for a normal week; event weeks need 4–8 weeks.
Observed pricing
On a 4,157 nm sector our fixed-price model quotes €78,500 for an ultra long range and €78,500 for an ultra long range in standard season — 1 cabin class clear the range and runway test here.
