Oh bubbly, bless... Didn't your mother teach you the old "different is ok" rule - just because your airline doesn't do it doesn't mean those other airlines are wrong or better or anything but just plain different. Rest assured that people are not able to sneeze in an airline without a plethora of people in far flung departments completing risk assessments on risk assessments - especially in our part of the world. This hasn't inadvertently been overlooked by everyone (apart from you) since 1996...
