Scenario 1: So you didn't fly either leg? In that case, call again using the dedicated PLT line, and ask to speak with AAdvantage Customer Service. Then, explain your situation. Tell them that you want ORC in lieu of a refund for the trip you didn't take. You should be able to get it.
Scenario 2: You might be able to get 4000 - 8000 miles here.
Scenario 3: No comp warranted, but if you tell them about this, it might strengthen your case for 8000 miles as opposed to 4000 miles.
In scenario 2 and 3, you would send an E-mail to Customer Relations, which is different from calling AAdvantage Customer Service.
Let us know how it goes. Good luck!
To clarify: In Scenario 1, I did fly the missing segments on January 29, a day I'd planned to be home doing work. So ORC is no longer relevant, but obviously there was major inconvenience and my loss of a productive day, in addition to the hassle factor, poor CS from the Gold agents etc. So given these facts, what compensation may be warranted?
Thanks for the advice on 2 and 3.
