Sorry, but I just want to set things straight because I consider myself an honest, law-abiding person. I have carried on my poles for about 15 years, with TSA’s blessing. They KNOW I have the poles, and they tell me that collapsible poles are fine. You might of course find an agent who exercises his/her discretion to prohibit them, but I have gone through at least 15 US airports and to Spain with no problem. I do always have a Plan B just in case — get to the airport really early and have a way to check them. But so far that has not been necessary.
I think it’s fine if people want to check their poles, but I don’t think it‘s nice to accuse people of being sneaky or duplicitous when that’s just not the case.
Except the TSA webpage does not differentiate between hiking poles that are "collapsible and in your carry on bag" vs "not collapsible and in your carry on bag". It simply says hiking poles are prohibited in carry on luggage with the same disclaimer that is listed for all prohibited items that the "final decision rests with the TSA officer on whether an item is allowed through the checkpoint". Yes - TSA officers use their discretion - as is posted on the website.
https://www.tsa.gov/travel/security-screening/whatcanibring/items/hiking-poles. The website clearly states that they are not permitted in carry on. Some people always manage to get them through security - other people get the same exact poles confiscated under the exact same circumstances, in the exact same airports, but with a different TSA officers. I have seen many poles being removed from carry on bags at security checkpoints along with other items that are clearly listed on the TSA website as prohibited items for carry on. And yes - sometimes they are in a side pocket and other times they are completely inside the bag when they are being removed.
And I didn't accuse anyone of being sneaky or duplicitous. I just think it is wrong to knowingly tell others to not follow the written, posted, TSA regulations. You want to risk your poles being confiscated - go for it. Just don't tell others to do the same. Honest and law abiding citizens "bend the rules" all the time. Heck - I am an honest, law abiding citizen, and I don't always stay under the legal speed limit. But I do know that I am not following the laws or regulations when I CHOOSE to drive a little faster than I am supposed to or bring something in carry on that I know might be confiscated. But I don't go around telling people that they should speed or disregard TSA regulations.
Back to hiking poles - I do think TSA needs to change the rules. Afterall - "walking aids" such as canes or crutches ARE permitted if they are presented correctly to the TSA agents as walking aids.
