Whenever I can justify flying business class to the UK I go with Malaysian. I do this mainly because three years after losing two planes in six months they still have to substantially undercut their competitors to attract corporate traffic, and only partly because the possibility of veering inexplicably off route before plunging into the Indian Ocean, or being taken out by a ground-to-air missile over Kazakhstan, adds a certain frisson to the interminable ennui of long-haul.
