A man died last spring on flight from New York to Miami, and his family says bad chicken is to blame. And now they want American Airlines and the catering company to pay them more than $1 million.

The widow and daughter of Othon Cortes, who died on the final leg of his trip home from Barcelona, claims he was poisoned by the chicken meal he ate on the American Airlines flight from Spain to New York’s JFK Airport on May 18.

Cortes, 73, complained of “discomfort and pain that included sharp stomach cramps and sudden thirst and other clear outward manifestation of severe physical illness,” according to CNN.

The deceased’s wife, Raquel, said her husband’s condition was “expressed and obvious” to the airline’s staff, the Miami New Times reported, but he was still permitted to board the plane anyway.

Cortes grew more ill during the flight, complaining of nausea and shortness of breath, and became unresponsive during a cardiac event. An emergency landing was made in Norfolk, Va., where he was pronounced dead.
