In this low rate environment, many people have chosen to open checking accounts with BankDirect. It pays a nominal amount of interest (0.05%?) but the kicker is that it also gives you 1 AA mile per month for every $10 you have in the account. With $100k, you would earn 10k miles per month. Over 5 months, that would equate to 2 RT domestic tickets. There are also various bonuses for direct deposit, debit card transactions, etc. If you have someone refer you, you get an additional 1k AA miles and so does the person who refers you.

If you would be interested in being referred, I would be happy to do so.
