Iv'e just extended BA by a day and now the only flight I can get is LAN Argentina EZE to Miami(763) and AA to Miami to Washington(738).

The only bummer is because I'm using points I have to travel Y class from MIA-DCA! I am using points for this RTW trip in Business Class and because AA calls its premium cabin First Class domestically I'd have to upgrade WHOLE ticket to F (meaning another 100K points) just to sit this sector in F. Argghhh

I am guessing from comments that LAN Argentinas 2 763's are identical to Lan Chile aircraft..service, food etc? WHich lounge do I use in Miami and is it a goody?

Thanks again for tips.
