Generally, people come here to complain about everything DL does to its customers. Many of the complaints I find to be petty annoyances with someone trying to get something for a minor inconvenience. This is the opposite end of the spectrum Today, I asked to change flights from China back to the US, pulling my departure ahead 3 days. I expected the worst - a change of fare class and a $450 penalty. Delta DM desk came through and only charged me the $450, waving the change of fare class. This was a very good deal, since the change of fare class would have been in excess of $2,000. Many thanks to DL! And take that, those of you who believe that DL is only about the $$$.
