I could have refunded/redeposited the ticket and then re-bought it since the space was still there, but I figured the hassle of cajoling an agent into doing what I wanted was less than having to refund/redeposit the ticket, rebook the ticket, follow-up to make sure CO tickets it, audit the refunds (miles and money), and contact AC to get the old seat back on the connection.

It did only take a couple minutes, so I think that was the right call.
