I am pursuing the Delta promotion and wanted to remind you that not all of the programs have the same restaurants listed, i.e., some might have more.
This came home to me when I realized that one of my local restaurants is listed in both the United and AA program (could be more but I have not checked) but is
not listed in Delta's.
It may be that Delta's program just has fewer participants, I don't know but I had been under the impression that the number of restaurants participating had been standardized among the programs -- I was wong, so I don't want you to be!
