It seems like there are always two sides on these two kinds of threads ("Is it okay to stopover in ____?" "Is it okay to vist ____?" "Would you fly on _____?". It also seems like those two sides are pretty consistent with those who have been and those who have not been to these places. I am actually fascinated to hear more. Also, are there any airlines, airports, places to visit that people who have been there will say, "I would NEVER go there again"?
