London → Tokyo

01Booking timeline

• Track from

  5–6 months out. Set alerts on your dates and a flexible variant.

• Window

  8–14 weeks before departure is where fares on this route have tended to be most reasonable. Peak dates run earlier.

• Last 3 weeks

  Fares generally rise. If you must book late, compare one-stop routings.

02Seasonal strategy

Cherry blossom (late March–April), Golden Week (early May), autumn foliage (November) and New Year. January–February and June (rainy season) are the value months.

Book blossom season as early as fares open; everything else has more room.

03Flexible-date advantage

Large — date shifts of a week around blossom season can halve the fare.

Weekday pattern: Midweek departures; avoid Friday outbound.

04Alternative airports

• Fly into Haneda (HND) for city access; Narita (NRT) sometimes prices lower.
• Manchester (MAN) via Gulf carriers can undercut London departures.

05Stopover options

• Doha (DOH) or Dubai (DXB) — excellent layover airports
• Istanbul (IST)
• Helsinki (HEL) on northern routings
• Seoul (ICN) — often cheapest one-stop

06Points, low-cost carriers and fees

• Points / miles

  Business-class awards via Gulf and Asian carriers are competitive; check partner availability early.

• Low-cost check

  One-stop options via Middle East or China hubs are usually the cheapest cash fares; factor in connection length.

• Bag & seat fees

  Most long-haul carriers include a bag; check seat-selection fees on economy fares.

07Arrival & jet lag

8–9 hour shift eastbound. Day flights arriving evening are the gentlest; otherwise force a normal first night.

Where to stay: Shinjuku for transport, Asakusa for character, Ginza for polish.

Airport transfer: Haneda: 20–30 min by rail. Narita: 60–90 min (Narita Express or Skyliner).
