Just called Delta. We leave in 13 days. Answer is still YES that Hernandez ceramics is considered a FRAGILE item so is acceptable by Delta guidelines.
(TSA- could / may have an issue with them, but explain what it is and should be ok)
AND ALSO....... (DO THIS!)
The lady I spoke with suggested to me to allow her to put a statement on my itinerary in their computer stating this fact. So, if there is an issue when I go thru TSA security, I can also have them check my itinerary on their computer where Delta is allowing it.
