We've seen a lot of downgrading in equipment on Air Canada from Canada to the U.S., mostly from Toronto. Obviously, AC's current problems are forcing them to revisit every route.
I was trying to book a flight from HPN to YYZ in August, expecting the CRJ. Instead, I saw it was a B1900D. Not too keen on that plane. I also noticed the B1900 for some flights to Hartford, where it used to be all Dash 8s, and now I see CRJs are being used YYZ-LGA, which used to be only A320/319.
What other routes have been downgraded?
