credit card- free miles

for those of you who get free tickets/mile points because of airline mileage points you rack up ..which credit card do you use?

i want to close 2 of my credit cards and get one good one that i can use, and eventually build points so i can get free or discounted airline tickets toO!

I have Continental miles through Chase for debit and my credit card.

Every purchase I make on my debit as a credit I get miles for and the same for a credit account I have with them for alot of purchases.

Ive heard that Amex is good for miles too.

DH and I use Citibank and get American airmiles. We were able to use our miles to upgrade all our flights to Hawaii for our HM. I think it's 26,000 miles for a free roundtrip flight within the continental US, and 15,000 miles to upgrade one way to first or business class. So far we've been pretty happy with them (we've both had these cards for years before we met each other). We're thinking about getting the Southwest one also though because we love going to Fla.

We used the American Express Delta card and got 2 round trip flights to florida, first class/business elite and it was only $37 each (you have to pay the taxes). But it took FOREVER to build up the miles (I think it was 180,000 miles). I would recommend finding a card that gives you cash back or gift cards like BJs, Amazon.com, or one of the other rewards programs. Try this site
