I stumbled upon this article this morning (if it has already been covered please merge with the appropriate thread) and thought it was worth sharing, as there have been several similar accounts with airlines as well as security staff lately.

As much as I am an avid supporter of dress codes and being appropriately dressed, showing cleavage as described in the article, or wearing a t-shirt with a statement (whether you agree with it or not) should not be a reason to be denied to board a plane. I am just as annoyed as anyone at people being dressed inappropriately or sloppily on planes, but when it comes down to it that is, in my opinion, a decision that's up to the individual. No shoes-no shirt-no service? Reasonable. Wrong shirt, no service? Come on now, people are trying to get places, not enter a country club. What's next, dress codes on the subway to work? What do you guys think?
