Hi, I'm new to this forum but from everything I've been reading is a lot of help!
I'm about to join a OneWorld program but can't decide which one. I am based on MEX (Mexico City) and travel roughly 6-7 times a year to LIM (Lima) and SCL (Santiago), and randomly to UIO (Quito) all of them are business related trips, so my company pays the fare but let me keep the miles.

I always travel in LAN so I'd like to earn status with them, but I'd also like to redeem the miles with tickets to the US. It's obviously more "expensive" to redeem with LAN than AA.

My main doubt is if I can accrue my miles with AA and earn status in LAN, even if none of my flights are with AA. LAN has a restriction of 4 segments with them at least to earn status, but I couldn't find anything related in the AAdvantage website.

Thanks a lot
