My wife and I both have miles in our Hawaiian Air accounts and Alaska Air accounts. We want to use our miles with Alaska Air. What I want to do is transfer our two Alaska Air miles to our two Hawaiian Air accounts. Then move my wife's Hawaiian miles to my Hawaiin miles (for free) so we have one account with Hawaiian with all the miles. Then move all the Hawaiian miles back to my Alaska account. This way at the end I have all our miles in a single Alaska account. Can I do that? Alaska doesn't allow combining of miles from two accounts for free but I believe Hawaiian Air does. We have way more choices using miles with one large Alaska account than two smaller ones.
