One more question - how many miles per year total?
I'm not sure, but I took a stab at it in post #9:
"As far as how much flying...hard for me to tell, because she doesn't always tell me when she's going somewhere. But I would guess that she covers significantly more ground than I do, and I covered about 80k EQMs in 2007. I would guess that she flies to the west coast 1-2 times/month, the midwest/south 1-2 times/month and then overseas 3-4 times/year. I would guess that she would end up in the 100k miles per year area."
What I should really do is see if I can get her to recall all of her flying in the last year (route, airline, etc.). That would really help, but I can already imagine the response I'll get just for asking.
The problem with multiple programs is achieving just low level status in each when in reality at least midlevel (e.g., *A gold) is where the best benis start to kick in.
I think that she could probably reach midlevel on one carrier and low level on another, or probably top-tier if she focused on one airline, but like I said... convincing her of that will be tough.
