What he was talking about isn't the same as the mini-RTW. 5T/7F/MO are three airlines you can redeem your AE points on, but you can never find them using AE's search engine because the process is different. I gather that you've never redeemed on these airlines so let me describe it to you:

You call up Aeroplan, you tell the agent you want to book reward seat(s) on 5T/7F/MO on certain date range between certain city pairs. They note them down and call the airline on your behalf and request seats. The agent then calls you back advising you of options and availability. If you don't like the availability offered, repeat with a different date range.

It's been a while since I redeemed on these airlines, so perhaps the request process is now more electronic between AE and 5T/7F, and MO is no longer an AE partner. However, when I booked with them, there was no booking fee.
