Hi, sorry to be a newbie, I've done some searches and can't seem to find this information.

I want to book two seats, but using 2 different aeroplan numbers. (My husband's card has just enough miles for one flight, and I want to get them used up.)

After I book these 2 seats, can I then manage these bookings on the AC webdsite like normal bookings, and rearrange our seats so we sit together? Or do I just do this when I book each seat, assuming that I'm taken to a seat selection menu when I book?

Thanks for the forbearance of the experts!
