thanks a million for your reply.

I'm going to be using AAdvantage program for accural as I've just gotten their credit card and would benefit me the most.

As well, I was overlooking the last part of the trip and realized TLV is Europe, and considering I'm using North America, South America, Australia and Asia, I'm unusure if I can use the TLV segment. I'd prefer not to pay extra so if worst comes to worst, I can eliminate this segment.

second part of question. I think if I fly via yyz-ord-yyc (calgary) would that force me to pay extra as it's an extra segment? This way I stick to AA metal and not Air Canada metal.

Thanks a million for your advice..

oh last question, does the ticket HAVE to be used in EXACTLY one year or can I extend it a few extra days (seeing that I'll be spending 11 months in Argentina)

YOUR HELP IS HIGHLY APPRECIATED!!!
