No easy way to get them out of the Alaska account, but if you fly you could credit anything flown on AA or DL to the Alaska Account until you reach a redemption level and then redeem.
Pardon the interruption but could you embellish on this? Meaning you fly on AS but can also list DL FF number?
Eventually I hope to visit Iceland and would like to select best way to earn miles.
