Would I Be Unreasonable to take a crochet hook on an aeroplane? I find it very relaxing, and it's more sociable than reading/listening to music (going with a group) because I can talk/listen to other people at the same time.
BUT would it be classed as an offensive weapon?
I've already checked the airline terms and conditions, and nothing even remotely similar (knitting needles, sewing/crafting equipment) is mentioned.
