Let's make it simple: If I book two biz class rt tix as per following, about how many loyalty points will I accrue? (have family in both, so not a total waste of $$)
AA BOS-HNL 10,181 RT miles $2645 biz class
AS BOS-SEA 5,200 RT miles $1250 biz class
Would that earn me 15K loyalty pts?
The AA roundtrip alone would: your earnings would be based on pre-tax fare x 7, given your current Gold status.
The AS roundtrip alone would not: your earnings would be based on your actual flown distance, with a 50% class-of-service bonus (assuming that you're paying a discounted Business Class fare) plus a separate 40% bonus for your Gold status, so 5,200 x 1.9, or roughly 9,900 miles/LPs.
Of course, in either case,
you would actually have to complete the flights by February 29, not merely purchase the tickets by then.
