London → Tokyo
Near a warning area, but does not cross it
Route assessed 12d ago
Viable LHR→NRT option, but the IST–NRT leg fully traverses the Central Asian corridor — the longest exposure to that congestion bottleneck of any option on this pair.
Very few backup paths if this route is disrupted
Check Eurocontrol Central Asian ATFM status before each leg. Delays on the IST–NRT segment of 45–90 minutes are not unusual during peak restriction periods.
London → Tokyo
8 to 30 days old. May still be right — double-check before you book.

Ranks below the HKG option because the entire IST–NRT second leg depends on the Central Asian corridor. HKG routing via Cathay avoids it entirely on both legs.
