I have not flown enfemme but before flying I would suggest that you become very comfortable being enfemme out in public. If you have not reached a very high degree of comfort out in public enfemme before flying then the TSA folks will almost certainly pick up on you discomfort and you'll get 'extra screening.' I've flown with my forms in my carry on luggage and other fem items and never had a problem. In fact, I've flown with almost no guy clothes whatsoever and never had a problem. Some day, I hope to fly enfemme. Until that time it will be underdressed in a bra and panties with bright red toe nails!
