when booking on MH website, since the beginning of the year I've always had to do some sort of check that involves sliding a jigsaw piece into the right spot. really annoying.
I've also noticed MH fares on AirAsia's website are sometimes cheaper than on MH website / app for the exact same flights/days ! haven't yet tried to book this way as still prefer to book direct, but may try for a less hectic itinerary one day.
