Tier Points on AA flights operated by Alaska Airlines
I'm flying to Seattle soon with American Airlines in First (Booking code is 'F'). However I have noticed that the flight to Seattle from LAX is operated by Alaska Airlines however is a codeshare with American Airlines. As my tickets are booked with AA, what will happen to my tier points on that sector?
(I'm aware that I earn 60 points per sector under 2000 miles in First.)
