The only reason I've recently got the card is to keep the mileage account alive. I still got 100K+ on the account from the days before I've switched to UA MP.

It is the only way I know to keep the miles from expiring (except from having status of course, and my curtsy FTL is going to be expire soon).

My e-mail confirmation though said I was approved for Platinum card (but with a line of credit way up from the $5000). The card has not arrived yet, so I do not know to what card exactly they have approved me for. On one hand keeping the mileage account alive with no annual fee is nice, on the other hand 30,000 miles for 79$ is not bad either.
