NEW YORK (AP) - American Airlines is disputing the account of a man whose cousin died aboard a flight from Haiti to New York.

The man says his cousin, who was having trouble breathing, was twice refused oxygen by a flight attendant. He also claims that medical devices, including two oxygen tanks, failed to work.

American Airlines confirms the death of the woman (Carine Desir), and says medical professionals tried to save her.

Airline spokesman Charley Wilson says there were 12 oxygen tanks on the plane and that the crew had checked them ahead of time to make sure they were working. He says at least two were used on the woman.

Wilson says he doesn't know whether a flight attendant initially refused to administer oxygen to her.

The woman was pronounced dead by a doctor on board the plane. A medical examiner says she died of natural causes.
