After the 5% cash back bonus period expired on my last credit card, I have been taking advantage of a few credit card offers to build up some frequent flier mileage in anticipation of a trip overseas.  United hubs in the nearest major airport, so I went with the Chase United Mileage Plus Visa. 

I have received a variety of offers from United for this card, generally for ~20k miles.  Ibut did some searching and found a better offer here: [1] http://www.firstusa.com/cgi-bin/webcgi/webserve.cgi?partner_dir_name=united_signature_25k_afw 

I made my first purchase on the card ($600 worth of graduate tuition) about a month and a half before my 25,000 miles posted.  When they did, I got a nice surprise: tuition payments are rewarded with double miles on this card! 

So I got 25,000 miles plus a $25 off travel voucher, a one-way upgrade, and scored an extra couple hundred miles for paying my tuition on the card.  All in all, not a bad deal.  I do, of course, pay off the balance every month though, and there is an annual fee after the first year, but I intend to cancel the card prior.  Read the small print if you sign up, of course, to make sure that you are getting exactly what you expect!

*I hold the aforementioned card but receive no compensation in any form from this post.
