Anyone booked an AM flight to South America with Skymiles before? The AM chart lists 90K for LAX to EZE RT in lie-flat J on 777 which seems like a good deal to me even if Aeromexico isn't the best airline. However, I can't find anyone talking about redemption on this airline even though it is SkyTeam. Related and kind of newbie question... I know PM/DM can cancel my award tix online with no fee (except inane T-72 rule). What about on Skymiles partner award tickets like this? Again, I know this is a newbie question, but I've only booked DL, KL, and AF tickets online and never had to cancel an intl award before. However, in this case, I have another trip booked that I would cancel and take Aeromexico instead if I can indeed secure an itn like this.
