2. The body of evidence about problems with the SkyMiles program offer possible improvements for DL. FT is a place where this is shared by people that fly a lot.
3. Posts on stickies get lost in the shuffle.
4. I am already staying an extra day to get a better fare, and cannot justify to my employer or sponsor to stay any longer to get a better fare.
5. Not sure why it is "bad form" to include the name of the customer service rep at DL.
