Air Canada is investigating after a woman woke up "all alone" on a "cold dark plane".
On Thursday Tiffani Adams recounted her experience in a Facebook post shared to Air Canada's page by a friend, Deanna Noel-Dale.
Adams says she fell asleep on the one-and-a-half hour flight from Quebec to Toronto.
When she awoke around midnight, the plane was "freezing cold".

"[I was] still strapped in my seat in complete darkness (I'm talking pitch black)," she wrote.
"As someone with an anxiety disorder as is I can tell you how terrifying this was."
Air Canada confirmed the incident occurred, reports BBC.
"We are still reviewing this matter so we have no additional details to share, but we have followed up with the customer and remain in contact with her," a spokesperson for the airline said in a statement to Associated Press.
Adams says her phone died shortly after she woke up and, with no power on the plane, she couldn't charge it.
"I found the walky-talky things in the cockpit but they also don't work I can't radio for help," said Adams.
She found a torch and flashed SOS signals out of the windows hoping someone would see her.
After that Adams opened the door of the plane to a 40 or 50-foot drop to the runway below.
"I hang out of the door trying to get the attention of ground crew...I search frantically for a rope so I can climb down safely.
"When I see the luggage cart driving towards me I am literally dangling my legs out of the plane, he is in shock asking how the heck they left me on the plane. I'm wondering the same."
She says the airline offered her a limo and a hotel, which she declined.
Adams says in the wake of her ordeal she has been "a wreck" and has had reoccurring night terrors.
Comments on her post are sceptical with people claiming she made up her story to get something from the airline.
"I'm pretty sure the pilot would have done a check of the plane too and the flight attendants at least to see if any personal items were left behind. Poorly made up story!" wrote one person.
