What you have to remember is BA are around 30-37 long haul aircraft less than pre-covid. The 787-10’s are having to cover routes they weren’t planned for (such as SEA, PDX, DEN) and other fleets like 777/787/350 have been drafted to ex 747 routes. Until their fleet number increases or KL becomes more financially beneficial to BA we probably wont see a return to the likes of KUL/ICN/BKK until S24.
