I saw the 'three year anniversary' and noticed the 'paper' bragging about how Air Canada (the airline that threatened a passenger with a no fly list if he wouldn't sit in another passenger's fresh puke) was going to fire all its pilots who were not vaccinated against Corona.
They must be having enormous buyer's remorse if they did, because at least across the Atlantic, there is an enormous shortage of pilots and personnel.
Just curious.
Things outside of their control(weather) or if they pull away from the gate then they can pull shenanigans. That's why you'll get boarded on a plane and then literally as the door closes they go "OH by the way we are going to be sitting on the tarmac for two hours."
