BofA also has the Alaska Airlines debit card (in addition to US Airways). (all these cards are listed in the finance section of
RewardsDB.com ).
One other thing to consider - many debit cards have a daily / weekly maximum limit of how much you can charge. I used to have the Citibank Premium AAdvantage Debit Card which as it turns out has a $2500 daily limit, the BofA Alaska Debit Card either has a higher limit or none at all (I can't remember).
