"I begged American Airlines every day to find the urn," she said.
The airline released a statement following the incident, saying, "When we need customers to gate check a bag, we always ask for customers to remove all valuables and important documents. Had we known there were cremated ashes in the bag, we would have had her remove them or found a place for the bag. We apologised for losing the items and certainly are very sorry for her terrible loss."
A spokesman for American Airlines insists the airline staff were not made aware of the luggage’s contents, saying Ms Pierre-Canel was asked to list the contents of her bag and their value but that the urn was not included.
Ms Morey said the urn was not written down because there was no way to assign a dollar value to her daughter’s remains but said there was an extensive email train showing the main concern was for that urn.
Nineteen days after American Airlines lost the luggage, they found the bag and returned it to Ms Pierre-Canel.
She said: "I went through it. I was screaming. I was hurt. I wanted to die because I felt that I failed my child."
"I failed her because my child did not die just once. I lost her twice."
She said her daughter’s wish was to have her ashes "spread across the sea in Hawaii, the South of France, off the coast of Venice, Italy and off the coast of Australia."
