I am very new at this FF miles thing, and I tried to read as much a possible, before asking a question that I am sure has been asked a million times before…I did not find the answer, so I apologize in advance.

We only fly for vacation, so we do not have tons of miles (about 50k). But we will fly to Buenos Aires next Nov (2010) and would like to upgrade. We will purchase the tickets, and plan to use miles for the upgrade only. According to the CO chart, we need 25K/person/flight (and some co-pay, depending on the fare type).

Because we do not have enough miles, I am thinking of applying for a Chase/CO credit card, that will give us 30K miles as bonus (recent email). However, before I do that – realistically, what are the chances we could actually get the upgrade, considering we have no status? We will fly EWR-EZE on a Sat morning, and return 2 weeks later on a Sat.

Thanks a lot
