It does look like DL are really trying to do what's right through all this. Just look at the homepages on the websites of the top four - BA, AA, UA, DL. The first three are all trying to sell seats at all costs, some of them even saying don't bother calling us unless your flight is within 72hrs - we're too busy. DL are focused much more on caring for their existing passengers and reassuring new ones, while still leaving the ability to book new flights top and center of every page. I know who I'd trust!
