Hey people!!! I have been an AAdvantage (One World) member for a long time know, yet know that Swiss has been bought by Lufthansa, maybe Star Alliance will be a better choice for me. Do you think United will survive?? Will LAN begin direct service to Europe from Argentina with "Lan Argentina"? Who do you think is best and more realiable in the long term?? Star Alliance or One World?? Consider I'm in South America, and more specifically, in Buenos Aires, Argentina! Thanks!
