I've had both the Starwood Amex and the Diners cards for years and they both have their merits - otherwise I wouldn't have kept them for so long. Another card that you may want to consider is the Southwest Visa thru First USA, for every $16K in charges you get TWO 1-way Rapid Rewards certificates that can be used with absolutely NO capacity controls - if there is an empty seat on the plane it's yours (there are a few blackout days). The certificates are totally transferrable so anyone can use them - heck, although I'm not necessarily endorsing it they can bring up to about $185 each on ebay! Depending on where you live and where your daughter goes to school perhaps she could use the certs to fly home to visit...
