Jeff,
Thanks for participating in FT. What I would like out of SkyMiles is more transparency. Frankly, I can't criticize the program too much because I don't know the details. I understand that Delta makes profits from vendors who offer miles. So, I would hope that Delta increases Saver seats available in proportion to miles distributed. If not, then the program is abusing its customers.
From my experience, awards are sometimes available, but I have had better luck with US Airways and United. I'm sure others have different experiences.
I look forward to using the Awards Calendar. I enjoyed it for a few minutes this morning.
