Air Canada is a launch customer for the A340-500, but they were also the LC for the -600, this was going to be the 744 replacement, that have since dropped that order and increased the -500 order. They are keeping all of theire 747's including the 4 from Canadian, and are looking to probably get about 3 more, this means Boeing is not totally gone at AC, The 767's are also staying on, and are one of AC's favourite planes, they have gotten about 3 or 4 more in the last couple of months. The 717 is also a BIG contender for the DC-9/737 replacement on the thin routes.
