What's funny is that Air Canada made big claims in the past that the 787s would open up vast new frontiers in South America, Africa, and Central Europe. Frontiers that they couldnt serve since they claimed they were limited by the 767s. Yet here we are years later, big talk with empty results.
Now they are claiming that the A321LRs and A220s will open up frontiers for them to do Trans-Atlantic and Central American flights respectively. Normally i'd say it's big talk, but since Air Canada is always looking to screw their customers at every level, I see that talk as being more believable since they will be able to cram more people into smaller aircraft frames, thus saving them money. They would then be able to redeploy some of their 787s and A330s elsewhere, but where that would be is beyond me with their thought process.
