Ada Guan had no idea she was 37 weeks pregnant when she boarded a May 11 Air Canada flight from Calgary to Tokyo with her boyfriend Wesley Branch.

As the plane flew over Russia, the 23-year-old started feeling pain in her abdomen, which became so acute the couple had to move to the middle of the plane and sit on the floor, Branch told Canada's CBC News. "We just thought it was a bad stomach ache," he said.

Three doctors on board attended to Guan, who was eventually relocated to first class. "When I got moved to first class, I could feel something wanting to come out," she told CBC News. "That's the moment I knew." At 36,000 feet over the Pacific Ocean, Guan gave birth to a baby girl, whom she named Chloe.

"I thought I was just gaining a little bit of weight," she added. The couple told Canada's Global News that Guan had taken a pregnancy test a month prior to the birth, and it came back negative.

The plane arrived at Narita International Airport 30 minutes early after receiving priority to land ahead of other flights. Once on the ground, the new parents and baby were rushed to a Tokyo hospital, where they received excellent care, Branch told CBC News. While they owe the equivalent of 2000 Canadian dollars in medical bills to the Japanese hospital, they plan to set up a GoFundMe campaign to help cover the costs.

The family will return home from Japan later this month, once they get everything squared away with the Canadian embassy. "I've never been happier in my life," Branch said.

Congrats to the new parents.
