I could care less whether anyone here thinks I am right or wrong. The point is that if AA claims that the product offered is an Expedia product as a reseller, then it's up to Expedia to make good on offering the flight on the Expedia product that I purchased. AA is irrelevant to me as purchaser of an Expedia product. Yet, Expedia and AA acted in the role that it's an AA product and Expedia is merely the selling agent of an AA product, from which the money flowed from me as purchaser to AA thru an intermediary agent to the supplier AA. Expedia is either a reseller or agent; it can't have it both ways and assumes one or the other depending upon which role it finds advantageous to it.

Regardless, I'm satisfied with the way I handled this, and whether anyone thinks my actions are over the top or time-consuming is irrelevant to me. I have not wasted any minute on phone calls; all messages done quickly via email. We all have different methods to achieve the objective desired.

Lesson learned: can continue to share experiences on Flyertalk, but recognize that there are some folks here eager to show how bright, smart, and correct they are.
