This year? Leaving today, BNE-TPE-LHR on Eva. In Sept, SYD-ICN with OZ, GMP-HND with NH, NRT-BKK-SYD with TG. Oct, PER-JNB-GRU with SA. More next year: Feb 16, SYD-BKK-NRT with TG, Apr 16, LAX-NRT-SIN with NH. This is in combination with other FFPs.
Last year, I did 4xJ(!) with SQ, SIN-CDG and ZRH-SIN (the good old days.....). ZRH-FRA-NRT with LH. NRT-YYZ with AC, YYZ-LAX-NRT with AC/NH, all with LM.
That ain't me. I only did one cancellation ever with LM. That was for a change of date (due to unforeseen circumstances) as it was cheaper to cancel and rebook. In fact I would advice my fellow travelers, as much as possible, don't cancel with LM. The hassles of calling LM and to get the taxes and fees back is a big headache. Plan well before you book. That is why I am already planning for my trip in May 2016.
I have more than 9 weeks worth of PDLs left so I need to burn it, that's why I am traveling around the world like crazy.
