Stretch..BA are the DFS of the airline world and there will be some sort of offer on a monthly basis for the rest of the year. September and on boxing day are generally the big sales in terms of hype if not deals.
Continental club…..not sure i would agree with you about LH. I have just done a quick check of LH fares ex LHR and FRA to CGK in August EX LHR the fares ranges from £2537 to £7149 for business with the majority of seats at 7149 around the 17th. By comparison fares ex FRA on the same day are just Euro 3588 or 3963 Euro at their highest.
HKG ex Fra is 3488 euro rising to 4998 euro but same flights ex LHR is £3089. ( This can be reduced to just £1900 if you are very flexible on dates though).
Bottom line however is that foreign ops take their lead from BA and whilst they may undercut BA, their fares are not the sort of bargains available ex Europe. BA in contrast must compete against them in a lower fare Europe, hence the huge savings that can be made.
