Yea I know. I need the MGM's to make Platinum otherwise I would go with LAN. I'm not optimistic that it will go off without a hitch. There is a later LAN flight I can use as backup if necessary. I'm flying in on Emirates from Rio and then to AR-what a change that will be.

I have since talked to AR and sent them my passport and now will only have to show the credit card at check in so it should be okay.
