I flew R/T PHX to LAX for a 3 day ASA
104 class a couple of weeks ago. Because of the flight schedule I did not check luggage, just a back pack & a carry-on, in which I packed my mustang pfd
with a xtra co2 cartridge.
After reading previous threads & posts as well as TSA info, I was confident there would be no issue if I checked the luggage. When dealing with the gate TSA people sometimes it's a crapshoot.
I printed up the TSA brochure as well as a email
from SW Airlines saying it was o.k., & put it in an envelope, in the pfd
Good thing. I was stopped & grilled in both airports with alot of "what's this", "I need to get my supervisor", "I have never seen one of these", "I never new these were in the TSA brochure", etc... Probably/Hopefully if I not had the printed info they would have checked their info, but you never know.
