The 33-year-old woman was assisted by a nurse and doctor who happened to be on board Royal Jordanian flight J261 when she went into labor.
The little girl was born at around 5:30 pm New York time on Tuesday, while the plane was cruising over the Atlantic, said Joe Pentangelo, a spokesman for the Port Authority of New York and New Jersey.
"From what the doctor said, it was a fairly straight forward delivery," he told AFP. The baby weighs more than 2.7 kilos.
Mother and baby were taken to a nearby hospital and are reportedly in good health, Pentangelo said.
The woman is a Jordanian citizen and was travelling alone.
