MXP can be very good, too - especially for £1600 business class to SIN.

In premum economy you're already very close or even above to the INCEU60 prices via Bangkok from Amsteram or Gothenburg for business class.

If going to Indonesia, route through Hong Kong (not sure if you can do that on BA, but you definitely can on Cathay) as HKG-DPS/CGK gets long-haul tier points (at least 70 each way when combined with a long haul premium economy fare).

Finally, there is/was a Sri Lankan business class fare to Indonesia earning something like 560 TP from Dubai for £700ish.
