Thank guys
Unfortunately it is not curable (and with a bad short term prognosis) and I will have to decide whether I stay in NL for the time being or that I return to Timor Leste and will fly back every couple of weeks.
Luckily reward availability from KUL on MH seems to be very open so at least that won't mean I need to go broke buying one-ways.
However, if at anytime a GGL is willing to offer me the use of their joker it would be appreciated. SIN-LHR is hard to get last minute.
