Aeroplan, Continental and Delta - all diff. names - all instant - you just need to sign out and back in to your account to see the points.
As for Delta, with promo's like the 20-25% transfer bonus, my personal experience was that the bonus posted instantly along with the miles (even though it says the bonus will post in 4-6 weeks) however a friend mentioned that his bonus points did not transfer instantly.
A word to the foolish, like me, who thought that the amount of points I needed to transfer to get to 100,000 with a 25% bonus, would be 75,000, but as you probably realized by now, this is not true. You would actually need to transfer 80,000 to get the 100,000.
