Light Jet · London to Tokyo

A light jet from Farnborough to Haneda is not a single leg. The category tops out around 1,800 nautical miles of practical range with four passengers and baggage, against a great-circle distance of roughly 5,150 nautical miles. Expect two technical stops on a northern routing, typically Reykjavik or Keflavik for fuel and a second call at Anchorage or a Russian Far East alternate such as Petropavlovsk when overflight permits allow, with crew rotation staged to keep duty time inside EASA FTL limits. On a southern routing through Dubai and Delhi or Bangkok, plan on three fuel stops and a night stop for the crew. Quoted block times of 18 to 22 hours airborne are realistic; door-to-door is closer to 28 to 32 with handling and rest.

Farnborough is the sensible departure for this mission. Slot coordination is straightforward, the CIQ desk is inside the terminal, and an 0600 local push places the aircraft into Keflavik within legal duty. Luton and Biggin Hill work when Farnborough is saturated, though Luton airspace delays in peak summer can cost an hour on the first leg. At the Tokyo end, Haneda remains the preferred arrival on business-aviation slots allocated via MLIT, with a strict 2300 to 0600 curfew and limited GA parking that requires prior PPR. When slots are unavailable, Narita accepts the aircraft without curfew restriction but adds an hour of ground transfer and a separate customs clearance.

Operators worth shortlisting for this profile run Citation CJ3+, Phenom 300E, or Praetor 500 equipment with crews current on North Pacific and polar procedures, HF radio, and CPDLC. Ask specifically about Russian overflight insurance, Japanese landing permits filed with at least 72 hours notice, and tankering policy at Anchorage where Jet A pricing moves weekly. For most principals, a midsize or super-midsize will retire the trip in one or two stops and under 16 hours airborne; we quote the light jet option honestly, with the caveat that the economics rarely favour it above 3,000 nautical miles.
