I have been on the Delta site looking for FF miles biz to Istanbul. I was shocked to see most of them at 200,000 miles!! Our last trip 2 yrs. ago to Europe was 120,000. We are about ready to cancel our Delta AMEX if this is going to be the case. When I called; they said it is a 3 tierd system. 100,000; 160,000 and 200,000 miles. Naturally everything I could find was the 200,000 miles reward. This is sickening! We only have 162,000 each and may end up canceling the whole trip. Has anyone else had this problem?
