Just wanted to pass along our experience... We have been using the Delta Skymiles American Express since 8/01 and managed to accumulate 175,000 miles/points. I was able to get three r/t tickets for our March 2005 trip to Disney for 25,000 miles each. The tickets would have cost us over $700!! We are pretty excited about the fact that we were able to snag some of the "limited" seats, because otherwise it would have cost us 50,000 miles a seat. Now we still have enough miles left for 4 more tickets. We used the AMEX to pay a lot of our monthy expenses and paid it off in full every month - we didn't incur a single dollar in finance charges in earning our miles. We were able to take advantage of their "double miles" promotions to earn lots of free miles. We are now switching over to the Disney visa card with a similar plan in mind. Its been a fun week... free plane tickets and under 30 days for our September trip!
