I'll second the comments here: the service onboard is great, but they make it unbelieveably difficult to buy tickets if you're not in Malaysia. I bought tix online one time and had to go back and forth between customer service on two continents and finally had to visit the rep office in DC to pick up my ticket
I booked some award tickets on MH through the Japanese WP office on a Saturday and had the paper tickets in the mail by Monday ^ It seems ironic that NW is better at issuing MH tickets.
