A few weeks ago you could go the opposite way to the east coast for $1500. Add in a stopover if you want and then go the the west coast for around 2k. I booked cph-iad over the summer. Dca-sfo sfo-dca over thanksgiving then back to Europe over the winter for 1920$. So if you are flexible there are options available right now. It was only $600 more for biz than coach
