The limits are per transaction. You can have one transaction per airline per day. So, it might take you a few days to transfer a large number of miles, but I don't think it's that big a deal in the grand scheme of things. I do think that this could be spelled out a bit clearer on the website, but my interpretation has been confirmed by our very own Starwood Lurker.
