I'm a pretty much a complete newbie to the frequent flyer game. I just switched to a new job that is probably going to see me flying about with much much greater regularity than my last job of 13 years.

So I would really appreciate the help from all the old hands here

I already have an AAdvantage and JAL membership, but I don't have any remaining miles on either and don't foresee using either very often anymore.

Thanks in advance!
