Air Canada was quick to say it'll try to help any stranded passengers, just like WestJet's offer when Air Canada hit serious labour pains in 2011. Air Canada says it is prepared to boost its capacity in the event of a strike at rival WestJet. On the labour front, the union representing Air Canada flight attendants is trying to organize WestJet cabin crews. When WestJet makes an announcement, Air Canada quickly follows. A collusion lawsuit was even launched after Air Canada took just three days to match WestJet's decision to charge for checked bags.
