people talk about the spg amex card for starwood as a good hotel card...

airline cards..it all depends on what kind of travel your doing...seems like everyone like continental the most on here...so think about getting their card..

in general from what i've learned...sign up for the big free bonuses(30k+) whenever you can...and try not to pay for any cards....getting any amex membership rewards card is pretty good because of the versatility of the points

also just review this site...
