An employee working at an airport takes four or five weeks of general training. As for flight personnel, they take eight weeks of training which are basically focused on safety. The training is also focused on service, but it is mostly on safety. Afterwards, an employee can organize his or her time to take up to eight days of classes per month in Toronto or in Vancouver, for instance, to maintain his or her language skills.
