I disagree vehemently with "better safe than sorry". Why fly at all? Staying home is safer, right?
I wish we could put all the people who would do "anything for 'security'" on their own flight and leave the rest of us who aren't going to lose our minds over incidents like this on other flights.
I'd gladly continue to fly to/from KUL and would fly MH if they were in OW, even if events like this happened daily.
