NATIONWIDE -- New parents got the surprise of a lifetime midair flying from Canada to Japan: a baby girl.

According to the couple, they had no idea they were even expecting a baby.

When the new mom started feeling pain, she was upgraded to business class and a physician, who just so happened to be on the flight, delivered the baby girl soon after.

The parents, who were originally on their way to vacation in Japan, named their daughter Chloe.
