And what I just learned in speaking with AA is they are given an allotment of seats only in Y, J and F for each Eva flight ....here I thought you could access the full inventory and sadly they cannot book AA codeshare using Evergreen Deluxe class..... so this really bites in my book. So much for the code share. And there was no availability any day to TPE out of SEA for June using the codeshare.

With the double miles promo I don't want to forgoe any extra mileage
