Hello all, I'm a newbie and have been enjoying reading these boards.

I just opened a CC with Citi for 75k on AAL and am looking forward to earning more mileage in hopes to earn enough for a trip to Europe in a few years. We belong to AA and Delta so I haven't yet figure out which one I should put the most mileage on. We live in Hawaii so would always get at least 2,000+ just to fly anywhere out of state. We generally do one trip a year, and always to the continental US. I usually buy the cheapest tickets which are normally on AA and Delta.

Basically, I'd like to find out how I could keep our sons two accounts active since he can't have a CC and I couldn't make purchases via his account in order for him to get mileage credit. What am I missing?

Any help on this is very much appreciated.
