When you travel with gummies I think it is best to put them in carry on. US TSA doesn't care about cannabis, they are looking for explosives, or weapons etc. however if it is discovered it will be discarded at best. I have traveled with it on occasion but usually leave it at home. I do have a medical card but that doesn't matter really to TSA. I have used an old pack of candy to put it in or kept them in my gummy vitamin bottle.
So while I think you would have no problem whatsoever, they are still technically illegal and could be confiscated.
