London-Kuala Lumpur: Singapore, KLM or Malaysia?

[gradeA]

Heading over to Melaka for work after Easter and wondering who PHers would choose...?

KLM: LHR-AMS-KUL, B777-200, seat pitch doesn't look great, good safety record though. Not flown with them before.

SIN: LHR-SIA-KUL, B777-200, good seat pitch, full cabins though, and means passing over destination twice each way!

MAS: LHR-KUL direct, A380 (most likely), possibility of slightly emptier aircraft but then there's last year in the back of my mind.

I hate flying enough as it is, so a good safety record usually sways it over price or flight duration (to a point). Alternatively, what are the Qatar/Emirates/Ethad options like?

I flew MAS two years ago on the A380 and it was as pleasant an experience as you can expect from a 14hr flight. I had also been thinking that in light of last year's events they'd a)be extra vigilant about safety, and b)possibly be less packed than Singapore (who I flew with a year ago). However, I am an exceedingly nervous flyer and MH370 and MH17 still stick in my mind (irrationally, I know...).

Just a quick update - work has booked self and colleague on MAS direct to KUL on the A380. However, I'm on the upper deck and he's on lower (both economy). Any likelihood that the flight will be under-populated enough to switch seats around at check-in?
