RE: fleet From https://en.wikipedia.org/wiki/Airbus_A330 it seems like the best customer is Cathay Pacific (Honk Kong).
Also total A330 is 1189 with 335 backlog - a big potential!
I think the money is when a major carrier like Air Canada will be influenced by Transat's decision. This will open the doors a lot more to companies like Cathay. Also, following your link to Air Canada fleet I can only imagine the potential if they are happy with the product! I would assume they will want to apply to all the fleets (14 of them)...
I guess that time will tell and I am happy to join in the wagon while the SP is low!
