Thanks for the replies. Looks like since American has a really big presence in cental and S. America I will concentrate there for now. I will have 5000 or so on American when I get back from Nicaragua the end of February and will be getting the the AA credit card (I assume those go toards elite status?) So will have a good start. I will no doubt be putting in a few domestic trips anyway this year which I will do on American and I might try a couple of quick mileage runs to see if I can hack it out and if so that will get me close to the 50,000 mile mark in March. Then I guess I need to look out for other offers and see where else I can go to build points/miles.

And, If it isn't for me then nothing lost but some time right?
