Air Canada says it’s looking into how crew members could have disembarked from a plane without noticing a sleeping passenger who was left behind.

The airline was responding to an incident involving a woman who described waking up “all alone” on a “cold dark” aircraft after a flight to Toronto earlier this month.

Tiffani Adams, who hails from St. Thomas, recounted her ordeal in a June 19th Facebook post.

Air Canada confirmed the incident took place but declined to comment on its disembarking procedures or how the passenger may have been overlooked.

Adams wrote that after she woke up, she called a friend to try to explain what happened, but her phone died and she couldn’t charge it because power to the plane was off.

She said she was “full on panicking” by the time she managed to unbolt a cabin door, lean out of the aircraft and call over a ground crew, who got her out.

Air Canada said in a Facebook response to the post that it was surprised to hear the story and “very concerned,” asking Adams to send a private message with her flight details.
