That does not count as a change? This said, I did not check on aircanada.com. On the operating airline, when the SAUA opened up, Z class also opened up according to matrix. Not sure if they have P at all, Z might have been OK with AC. The other thing, in the current context I did not feel like being on the phone for an hour. Also, the miles were from my wife's account, with much more restricted use.
