I don't think she would get through with knitting needles. My mom, an advid knitter, crocheter and quilter, flew from Toronto, Ontario to British Columbia and had all of her knitting and little quilting patches in her carry on to keep her occupied during the flight and she was not allowed to take her needles, or her mini quilting scissors on board.
She was pretty upset because those mini scissors were expensive and you can only get them at a quilting shop. The needles are easily replaced though. It's hard when you get to the scanners and they won't let you through with something because your luggage is already gone and you have to just surrender it.
I wouldn't take the chance unless it's cheap needles she can easily replace if they are confinscated.
I really don't know too much about this, but I think i've seen plastic knitting needles, those might be allowed--and i say might because again i don't know too much about restrictions other than they really tight since 911 but if you can find plastic ones there's got to be a better chance.
A lot has changed since 911 but it is a shame that people had too loose their lives before changes are made. I recall the FAA permitted passengers to bring on airlines
a pocket knife that had a for inch blade or less( check this out to see if I'm correct). When I fly I bring as little as possible on the airplane. I hope you have a wonderful flight.
Since 9/11, things like scissors of any size, any kind of knife, metal nail files, metal pointy hair clips, knitting needles, crochet hooks, can /bottle openers, fingernail clippers, etc. are not allowed in carry-ons. I was boarding a Southwest flight in New Orleans after a cruise on the Inspiration in Dec. of 2001, and the lady in front of me had two knitting needles and a large crochet hook confiscated. The guy in front of HER had his Swiss Army knife confiscated. (He also ended up against the wall and the airport police were there in a nanosecond. It was quite a scene! Made me really want to fly home...!) You can put those items in your checked luggage, but not your carry-on. If they are confiscated, you can have them mailed back to you...for a fee and a lot of paperwork. Take a look sometimes at the bin that's filled with confiscated items when you go through the scanners. Scary!
My Mom flew to my brother's in June of 2000 so it was BEFORE 9/11 happened, that's why it's so memorable because we were all surprised because in many other instances flying within Canada, the airline security was pretty lax, not so anymore. When we fly out of Toronto, on April 9th for our Miracle cruise we were told to be there no less than 2 1/2 hrs before our flight and be prepared to be thoroughly searched and be ready for lengthy lines, and our flight is 6:30 AM.
Well, I'd rather have the security tighter just in case.
