I just recently travelled with my featherweight from Florida to New York. I kept nothing sharp in the FW case. Needles and such went into my checked baggage. I did carry my FW on-board with me. Going through security, I was 'targeted' and pulled aside. I explained to the very nice officer exactly what I was carrying and he regaled me with stories from his childhood of his mother's Featherweight!! He was appreciative of my FW's great condition and let me continue on my way! Safe travels!!
