I for one would like to apologies for all rude American aircrew. Delta used to be one of my favorite to fly "company" on, they were the most likely to upgrade me when they saw I was repositioning.
As I understand with the NWA merger much Delta MGT is now NWA, NWA was an ugly demise, the bitterness during their hard times was evident (union busting, hardcore tactics). TSA mandates that allow a FA to call for an airmarshall if you complain about the brand of peanuts or other services provided. A standard of empowerment combined with a feeling of company impotence is certainly at hand. (exaggeration and sarcasm should be respected in this post, to an extent)
