I just received an e-mail from US Air offering a bonus of up to 100% if you "share" up to 50,000 miles. The bonus goes to the recipient. Fee is 1 cent per mile plus a transaction fee of $30 and tax. Here are the terms and conditions. I don't see anything about the offer being targeted. They say this offer does not apply to Buy and Gift transactions. If I understand this correctly, the miles being shared come from your account? So if you have only (say) 30,000 miles in your account, you can share no more than 30,000 and those will disappear from your account? It does seem a good deal if you know someone else who has a Dividend Miles account and one of you has at least 50K miles in your account. You could "share" 50K miles from your account with the friend, the friend actually receives 100K miles (and you lose 50K miles); the friend then does the same by sharing 50K miles from his account with you, and you receive 100K miles with the bonus. In the end, you each net 50K miles for $530 and tax, or slightly over one cent per mile. Am I missing something?
