If you have a beard ,wear a shalwar kurta, occasionaly have a topi , then beware, dont travel or you will be detained , thats the latest attack on muslims. I advise all muslims to travel only on airlines that are originating from muslim countries, that way you are less likely to be harassed and called suspious behaviour or terrorist. travel on saudi airlines, kuwait, malaysian airline, etc. even if you have to pay more, becuase it means people are less likely to look at you suspiously and you dont have be worried about being a muslim .
