Hard lesson, 101...
You can't bemoan DAL for raising prices. Have you flown on DAL lately? They're packed. Jim is right on the mark, its the rule of supply and demand. DALs first class is ALWAYS full. Those aren't free upgrades either. Business men and women are paying the price and Delta is only too happy to oblige. nbmcg01, don't wonder about fare increases. In a little while the fuel surcharges will start being added due to the market knee jerk over the sunken oil rig. In a little while you'll think $400 is a good deal. Now breathe, stay calm...
