The only reason to create a new account would be that because they are full fare flights, I would obtain gold or perhaps the top status on Eithad with these flights alone. I would like to book an awards vacation to Australia or similar very soon, the 240k ish miles im estimating that I would obtain would be very helpful for that. I heard Eithad has a better redemption than AA? If I used my AA number would those miles be elite qualifying for AA program or just redeemable? Thanks for the quick reply!
