I know there are a few threads asking about the boarding pass function of the Apple Watch and TSA, but I am wanting to get a poll on leaving the watch on to go through the PreCheck metal detectors. I like to sail through TSA quickly so I preload all my belongings into my carry on before even going into security, and have only my phone and ID left in my hand. As soon as they are scanned at the PreCheck checkpoint, I put them in a pouch on my backpack and I'm good to go. I fly a lot, and only one airport has been a problem with this approach, Boston's Delta terminal ... their metal detectors go off with my Bostonian dress shoes so I have to argue with them that I need to take them off, when they are confidently demanding that I leave them on. Went through that experience over 100 times in the last couple of years and was quite frustrating. Every other airport I've been to my shoes were not a problem. But I digress. I just got a Stainless Steel Apple Watch and would love to leave it on to go through security. Taking it off always makes me nervous about a drop to the floor. I'd rather not go through with it on and have the metal detector go off, and end up putting it in the bucket. It takes a lot of time and slows down the process for everyone, and I also don't want the watch to disappear while TSA is being slow letting me through. So, I pack it away. So has anyone worn their SS AW through the TSA Precheck scanners regularly? Any problems? Thanks.
