Update, I used Aeroplan miles to book BWI to SMR in business class on CM with a connection at PTY 5 days before departure. The weird thing is that this could not be booked through Mileage Plus or LifeMiles, Aeroplan only. I did learn something new though, you can now cancel LifeMiles awards online which is very cool as I cancelled my IAD-BOG-SMR flight for the first time ever online. Since there was a schedule change, the system didn't even charge me the $30 per passenger cancellation fee (I booked the highest bucket ticket knowing I may need to cancel).
