By the post above N class are nil miles earning AA, so just go with Alaska ffp
Alaska has many partners and you may get value from the miles earned on your trip
With LAN you will have orphan miles, that will be hard to use
YQ is fuel surcharge on award flights. Is a very high $ on flights using the QF, BA and some other freq flyer programs. Do not confues taxes with surcharges
Edit Post 14 below, N class on QF does earn AA miles
