I Been flyin on Delta for many years (20+) and getting miles. It started you get 20,000 you get a free domestic round trip. Them it goes to you gotta have 25,000. In 2002 I had 27+ and tried to use them to go round trip Kans City to Miami. The reservation suggested I pay $208 this time and after this trip I have over 30 and that entitled me to an international RT. I now have 34720 but now it takes 47000 to go to cozamel and 37000 to domestic Miami. What good are they. There word and policies are no good.
