That flight was the return from Tokyo (RJTT) to London (EGLL). Due to the closure of Russian airspace, the outbound flight is longer than pre-war as we fly over Turkish airspace. Due to the wind patterns, it is almost always longer flying westbound, so we usually fly east both ways.
In this case, the weather at one of the ETOPS alternates that we use (Shemya, https://en.wikipedia.org/wiki/Eareckson_Air_Station) was out of limits, so we had to fly back Westbound with the associated headwind and longer flight time.
