A student of mine who was flying to Seattle from the East Coast inquired if he could bring his inflatable PFD with him with the Co2 cartridge. Not knowing the answer, I posted the question on Facebook and immediately received 30 comments.
The TSA lists on their site the following info:
Small compressed gas cartridges (Up to 2 in life vests and 2 spares. The spares must accompany the life vests and presented as one unit) – OK for Carry-On & Checked Baggage. http://www.tsa.gov/traveler-information/prohibited-items |
Many who posted about their experiences said they had their cartridges taken by TSA officials. One had the entire waist inflatable PFD taken as well. Some had a few positive experiences.
