Oneworld Alliance Flight Pass, Already in Argentina

Hello everyone! I'm a university student studying abroad in Argentina for the spring semester. I'm already here in Argentina, and I just found out about the Oneworld Alliance Flight Pass. Does anyone know if I can still buy one even though I've already arrived? I flew to BsAs from Los Angeles with LAN airlines a few days ago. I plan on traveling through Argentina, Chile, Peru, Ecuador, and England during this semester and summer so this pass would be extremely helpful since money is really tight. Thanks!

No, you can't. Read the third point of the Terms and Conditions of the South America pass in the web of Oneworld.
