BOA usually has weak offers. Consider Barclay cards they have IHG and Wyndham among others.
Discover has a good cashback offer. Amex has many good cards and they run good bonuses on at least one just about every other month....if not MR point card, DL card or SPG...
keep an eye on the FT boards or your favorite travel blog for the newest, biggest offer.
I like this site for its wide variety of bonuses and offers...it doesnt always have the latest or best offers listed but it does catch most of them and has a lot of info...probably even cards and banking bonuses you've never heard of.
