I have taken it on more than 6 flights this year including to Mexico and Germany and had no issues. The key is to put it all in a gallon plastic bag and put it separately in the bin with food items. If they ask what it is I tell them kratom tea. It's legal and even if they check it with the drug scan it's clean. Just don't go to any banned states :)
I don't see why not, it is not illegal, however I am not a TSA agent nor a police officer so I truly can't say for sure, but a co worker of mine took kratom with him on his trip to CA a month ago and he had no issues. Hope this helped.
I've flown to and from TX. My checked bag was searched and kratom was no problem. I don't carry in my personal bag as I dose before boarding.
