Are metal knitting needles allowed in carry on luggage and or checked baggage?
TSA out of LA to Leon permitted them.
Checked luggage-yes. so just put them there.
Knitting needles are specifically listed as an allowed item. My wife always travels and knits. Never had a problem. Look at TSA banned/allowed items list and you will see.
If you are flying internationally the rules are not be consistent for carry ons. My wife is a knitter, and she has had no problems leaving the US. However, flying home from Mexico, security in Cancun would not allow her knitting needles. Flying out of the UK or France, usually no problem. However, she now travels with bamboo needles (she is a sock knitter) and has had no issues with security.
The safest is to use wooden or plastic circular needles if you want to carry them on. Any kind of needles can be packed in checked luggage. I prefer to use straight needles, but always transfer to circular just for the flight, to be sure I won't have them taken away!
Just got back from Los Cabo’s to the US. TSA took my metal circular needle , crochet hook and a small pair of scissored. They do what they want. Can’t fight it either.
Necropost, so I will add to #6 - there is no TSA in Cabo.
