Was interesting getting a refund for an unused refundable ticket. Very easy. Wondering if they're using the US code to handle. Requested a refund online for an unused AA ticket. Next day received an automated notice of refund approval from US e-mail. The amount and information were all correct. Following day received a similar e-mail from AA. Glad the process was quick and painless. Lesson learned was wait until the day after you cancel to make the request. Requesting same day results in an error. A call to the web services group lead to an unhelpful/unknowledgeable person who insisted the ticket was not refundable. Waiting until the next day resolved the error.
