As an original poster writes:
Has anyone applied for TSA Pre Check for baby? Is it even needed if both parents already have it?
"My wife and I both have pre-check and have flown twice with our infant son without any issues. According to TSA website, children under 12 don't need it to travel with an adult with PreCheck. Hope this helps!"
"We have pre-check but our daughter doesn’t, and we haven’t run into any problems with her. So far she has been on 6 flights without incident."
