Back in 2011 I had LAN booked on JFK-YYZ-JFK and they cancelled the route. I ended up going from a LA 767 to an AA CR7.
This Christmas I had BOG-MIA booked on a 787 in J with avios. They cancelled the route. I ended up having to buy Jetblue coach out of pocket.
Then this April I had LIM-IAD booked in J. They cancelled the route.
I really hate this airline.
