Yeah you know that's what I thought as well and queried it with the CSA. I can't really understand this at all but they have ticketed it and taken my money so I'm guesing I'm safe but it is for this reason that I am really very reluctant to kick up a stink with AA about it. If they don't allow the extra segment purchase and they won't allow me to finish it in AMM it really screws me up and means buying a AMM-KRT-AMM separately at about $900.
