Hate being the newbie, but feel like I have to ask now. I'm planning a LONE4 for 2014 and obviously want to get the most out of it, since it's a lot of money for my gf and I.
I feel like AAdvantage might be best for us, but maybe there's other options as well?
Question: My gf and I are both doing this trip. Can we collect all the miles on 1 account, or do we need a separate AAdvantage number? I.e.: can I steal her miles?
