Last night I decided that I needed to book a one way trip from Ottawa to Toronto for Tuesday afternoon of this week. I certainly didn't want to pay for it, so I navigated over to Aeroplan.com, logged in and did a search.

Wow! About 5 flight choices. Some for 11,400 points, and better ("Classic Plus") for 14,500 points. The 2PM departure I wanted was 14,500 which...I guess is OK. So I chose the 2PM, entered all my details. End result: "A problem on our end... EC=NOPNR". I tried again, same deal.
