A flight attendant awarded for her heroism after the Delta Air Lines crash in Toronto earlier this year is now suing the company, alleging it “cut corners on safety” and knowingly put passengers at risk.

As many as 21 passengers on a flight from Minneapolis were injured when the aircraft went belly up on the tarmac at the Toronto Pearson International Airport on Feb. 17.

Six months after a Delta Air Lines flight crash-landed at Toronto Pearson Airport, a U.S. flight attendant aboard the plane is suing the airline and its subsidiary.
