Sooo I've gone back to the first time I posted on this thread and am going back to try to compile all of your helpful notes and tips into one place. I cannot thank you all enough for all the advice so far.
BUT
I have just now been researching JAL vs ANA and I think I'd rather go with JAL! I think they offer more nonstops between LAX>NRT and KIX>LAX (which is what we did last time) and based on the very tentative itinerary I have put together, I think that's what I'd prefer to do for the upcoming trip.
So now, while I am still definitely doing the CIP for the 80,000 UR points, I have another goal of acquiring enough AAdvantage miles for JAL business class. According to some recent (2019) articles I am reading, this will require 240,000 AAdvantage miles. Is this possible to do in a little over a year, do you think? Without going way over my normal spending habits? I've seen posts about the grAAvy train but I don't know whether that's a reasonable, achievable goal.
Thoughts? (I am running to check the reddit thread right now)
ETA: As far as I can tell, the reddit thread indicates that the best signup offers are via mailers. But there is a 70,000 AAdvantage miles Citi card application link on a website that I shall not name here because I know you all hate it.... I have learned that much! That's 10,000 more Miles than the email offer I got (I do have an AAdvantage account, although like the others it's empty). Is the 70,000 offer about the best I can hope to get? It's for the CitiBusiness® / AAdvantage® Platinum Select®World Mastercard® .
