You may want to call delta and see if you can pay the reticketing fee and get the difference in price back in travel vouchers. When prices from seattle went down this week, my friend who was in the same situation as you, called Continental and ended up getting $900 back less about $200 in penalty fees. While she didn't get the cash back-$700 in travel vouchers is pretty sweet. Good luck!
