No I don't want people to be required to and feel they need to dress up for flights like suits and ties and dresses. However, sometimes the issue isn't even the clothing it's the person's general appearance. The number of people getting on a flight that look totally unwashed, unkempt and wearing unclean, unkept clothing is astounding. You can dress in a tee shirt and jeans and look good. The difference are the number of people that think their clothes can be worn for days on end without laundering, they don't really need to take a shower in the morning, or they should replace clothing when in tatters and forget about having a healthy weight. Air travel reflects the downhill trajectory of society.
