Pardon my not posting this sooner, but @home went down as I was originally attempting to post this response earlier today.

I am sorry if I misread certain details of your two posts, but the 2-year reference in your second one led me to interpret that the various MCOs were accumulated over that period of time, not in single ticket exchange. In closely re-reading, I can now see that it appears the ticket you originally had [valued at US$1,700] for which you received an [AC?] ticket, and the balance refunded in these MCOs, in exchange was issued by AA. Is this correct?

As for my always defending AC, you should ask those who have been reading this and the Cdn forum before it for almost a year-and-a-half, who can certainly point to many critical posts about the airline from me. And just two weeks ago, I agreed that there appears to be both a senior management problem [i.e. no accountability to shareholders due to broadly held nature of shares] and a very technocratic rather than people-oriented approach to dealing with day-to-day operations.

That you have now admitted to having been tagged as a "difficult customer", and your non-response to the question about the status or outcome of the earlier suit against AC, has not changed my initial view of this matter: we simply do not have enough facts to determine whether AC is acting correctly or incorrectly in your case.
