Does this mean it's okay to wait until the renewal AF posts (which I guess is 12 months since account opening) and then call to cancel? As long as this is done within 30 days of posting, the full AF will be refunded, right?
It's actually within 30 days from the closing date of the statement on which the AF posts. I had no clawback from my PRG bonus when I closed it in this manner (immediately following my first renewal AF).
