Sarah Blackwood, a member of Canadian alternative rock band ‘Walk Off The Earth,’ says she and her 23-month-old son were booted off of a plane by United Airlines flight attendants because her toddler was crying too loudly.

In an interview with CP24 Thursday afternoon, Blackwood, who is seven months pregnant, said she was on United Airlines Flight 6223 travelling from San Francisco to Vancouver on Wednesday when she was told to get off the plane.

According to Blackwood, her son had been fussy and was sitting in her lap when a flight attendant warned her to get her child under control.

As the plane was taxiing, she said it suddenly stopped and the captain said the plane was turning around to be refueled. She said the child was fast asleep in her lap when the plane arrived at the gate however a flight attendant came to her seat and asked her to leave the plane.

"My son at this point was fully asleep on me, like knocked out cold and he would have slept for the whole flight," she said.

Blackwood said when she inquired about why she was getting kicked off, she was told the flight attendants felt “unsafe” because her son was causing some type of “threat to the plane.”

Flight attendants promptly escorted her, her son and her nanny off the flight, Blackwood said.

"I stood up, I was crying, like welling up with tears. I was so embarrassed," she said during a phone interview from Vancouver, where the band is performing Friday night.

"I just couldn’t believe that someone could do that. I was shocked." 

In a statement sent to CP24 Thursday, SkyWest Airlines, which operates flights on behalf of United Airlines, stood behind the crew’s decision to remove Blackwood from the aircraft.

“The crew made the difficult decision to remove Ms. Blackwood and her child from the flight based solely on safety concerns. Despite numerous requests, the child was not seated, as required by federal regulation to ensure passenger safety, and was repeatedly in the aisle of the aircraft before departure and during taxi,” the written statement read.

“While our crews work to make traveling safe and comfortable for all travelers, particularly families, the crew made the appropriate decision to return to the gate in the interest of safety.”

Blackwood, who said she was sitting in a window seat, contends that her child was not roaming the aisle as the statement suggests.

"He was on my lap the whole time. He was very squirmy but he wasn’t running around anywhere," she added. 

The flight crew, according to Blackwood, also threatened to kick off other passengers who were coming to her defence.

"The other people on the plane stood up as I was leaving and said, "Don’t leave. This is ridiculous," she recalled. 

"I’m pretty sure (the flight attendants) knew they were in the wrong right off the top."
