A Brooklyn man who claims he suffered the nightmare of all lost-luggage stories is demanding millions from American Airlines after it allegedly misplaced his deceased wife's body for four days.

According to the lawsuit, filed last week, the body of 57-year-old Teresa Olaya was so badly decomposed when it finally arrived in Guayaquil, Ecuador, that her grieving husband, Miguel, had to forgo a traditional open-casket funeral.

"During those days, a thousand things went through my mind," Olaya, 60, told The Post. "Where is she? Is she dumped somewhere like an animal? And I had no answers for my daughter. She would ask me, 'Where is my mami?' "

The awful saga began on March 28 when Olaya lost his wife of 26 years to pelvic cancer. He made arrangements with a Brooklyn mortuary, DeRiso Funeral Home, to fly her body back to Ecuador.

DeRiso, which is also named as a defendant in the suit, did not respond to a request for comment.
