ORD is also showing up with fares of ~$1970. Looks like it is only bookable via Delta but you can get KLM or AF metal if you want for a few extra dollars. You can route on all DL metal (albeit 764 for long haul) and use Pay With Miles to give yourself a nice little discount. I was able to pull this fare up starting in August as well.
