Yes ForresterModern, with a great kilt the usual idea of wearing a belt, extra material and all the folds of cloth that they would have to examine would make it difficult and require time for the TSA agents to make sure you pass inspection. As I stated before the agents were also sensitive to my informing them of my bonnet being my kippah and I also recall them asking if it were even possible to remove my belt (for those truly wearing a belted plaid but only the bottom part). I think that a non metalic belt would help in those conditions. One other thing for food for thought is the idea of comfort and sitting in a kilt in a confined space for a long duration. I have not been kilted under such conditions since I usually am walking around more so kilted. Sitting comfortably for an seemingly indefinite period of time during and between flights can be a little unnerving since you have to be constantly aware of not flashing others while trying to maintain comfort. And for those who may wonder...I was fully kilted for the whole weekend for the first time (which really saved on packing in my backpack) and traveling one way to my destination through three airports and two flights initially I decided to go regimental. Doing so, I was constantly worried about the occasional "flash" that was possible and had decided that for overall peace of mind and I decided that given all the things I had to be concerned with, I was personally better off in this case of not having to worry about that issue while I could focus more on making my connections and getting up and down from seats quickly. That would be also for a great kilt with all the extra cloth unless you were very comfortable with dealing with such issues.
