Here's another data point.

2 months ago, I booked a leisurely trip to Dallas for this week, departing on 3/24. Booked into I class. Cancelled my flights a few days before departure. AA cancelled the return flight after I cancelled my trip. Yesterday, AA's refund page gave me the option to move forward; it was the first time I didn't see a "pending review" screen. AA offered me a voucher at 120% the value of the flight or I could get a full refund. I'm confident that my ticket was not fully refundable. But, I have confirmation that the entire ticket amount will be returned to my credit card.
