Under 5 CPM I'll consider - ex-ANC its a bit spendy. Sometimes its higher or lower - like to spend some time at the destination- if DCA is under $400 on AS... I'll probably fly it. Adding the companion cert can help- especially for peak travel.
3 CPM is threshold for EQM partner carriers - AA & DL specifically - and if I can get a codeshare operated by AS...better
Under 2 CPM and I ponder adding something besides AS+partners but haven't bit yet
