as long as u manage to switch from aa to LANPASS, i dun see the problem. AUTOMATIC UPGRADE sounds like a great deal to me.
Too bad I can only make it up to silver premium status..
i live in BA to, and LAN is THE best airline i've taken to travel to the states.
I personally hate to go thru immigration on my first stop it the us and check everything back in...
LAN makes it a lot easier for those who travel to LA alot
JFK is a totally different story now.. I do prefer AA on dat one.
