I actually didn’t see your message and decided to try to 6 of my 2 oz bottles on a plane. Put them in a clear ziplock baggie and had absolutely no problem. They let me right through…didn’t even check them. Maybe it varies from airport to airport but neither airport seemed to care at all. I also brought baked coconut flour bread in tinfoil and they didn’t care about that either LOL. I actually had a good experience at the airports on my trip! Who’d have thunk it?
