Keep in mind that this offer cannot take advantage of the low fees for the Everyday Checking account, SunTrust's basic checking account, and instead requires Balanced Banking or above, checking products that impose at least a $12 monthly fee for checking and other SunTrust accounts that, in total, fall below $3000 (not a daily average--and other products impose higher fees and minimum balance requirements). Not bad if you intend to maintain a decent balance with SunTrust or already have some other accounts there, but certainly a factor to throw in when calculating whether $75 plus possible monthly fees are worth 30K Delta miles to you.
