The airline that made headlines last year when it lost pilots to a mechanical failure has announced it is cutting 400 jobs across the two nations in an effort to improve its training procedures.
The Southwest Airlines pilot training program has been under fire since September, when a flight attendant accidentally landed on a runway and was unable to respond to crew calls.
The airline has said it is working to fix the problem and has put in place several measures to make sure it never happens again.
A Southwest spokesman said the company will continue to train pilots to fly planes with the new rules and that Southwest is working with the Canadian and Mexican governments to address safety issues.
The airline, which has lost more than a half-million jobs in the past decade, has not said how many jobs will be lost as a result of the pilot training changes.
It has not released a timeline for the pilot changes or the timing of when they will take effect.
Airline pilot training is a key skill for pilots and airlines as they seek to compete in a rapidly changing aviation industry.
More than one-third of pilots train for the job in the United States, according to the U.S. Department of Labor.
