I think DM is useless. I have been DM for 11 years. Late last year I gave up on continuing with my Delta loyalty. The constant roll backs of benefits and service at every level is just sad. I used to really enjoy flying Delta and that's after flying 1k at United for 4 years prior.

This year I've split my flights on the three major airlines and had an equally frustrating experience. Quality customer service no longer exists.

United always has a better value for spending miles for flights. Delta has horrible redemption values. The Delta app is the worst. It has become worse over the last two years. If not for the Diamond customer service line, Delta's IT would grind everything to a halt. The DM line might be the only good thing happening, but it wouldn't be necessary if IT new how to code the app.

I flew Delta every week for 11 years. Now I dread traveling. Looking forward to staying home more.
