Hi,
I've been accruing miles mostly on UA though I want to start branching out to other programs just in case. I find UA and AA to be the most appealing programs in terms of networks and prices (flights to Asia/Europe).

I want to really start honing in on an airline (I have mileage in almost every major airline) and have been looking for articles regarding the financial viability of each airline (though I will probably still accrue some on UA for a nice reward). Anyone know of such?
