I am advised by an AA agent who was very knowledgeable about things oneworld, that there truly was a desire to assist CP.
However, the fact that AA had already maxed out the foreign ownership allowance, precluded any equity assistance. That, combined with CP's crushing debt, led them to believe that any other route to assist CP would be futile, would lose buckets of money, and was destined to fail, simply prolonging the agony.
Having just met the agent, I can't really vouch for the accuarcy. However, the overall knowledge, and the opinions expressed during almost 2 hours of discussion, cause me to give the agent some credence.
