I really hope that Delta is keeping track of how freaking awful the India customer service is. My co-worker who is now traveling with me almost 75% of the time (not a medallion level yet) and he wanted to book a M,B,Y class so he could book a mileage upgrade. He called the first time and got India and the guy there said that there now flights out of LAS that day that had any of those fares.

I called up SMS and within 3 min the US agent had found 3 flights that he would be able to get that upgrade on.

He would have ended up getting a super cheap fare rather than the M fare thus loosing money for Delta.
