I have a friend who has been hawking midwest-Europe rates for July since early fall, and 1K is the best it has really been--you have not missed out on anything. He is all excited to find Icelandair out of MSP suddenly drop into the $800 range, and he booked it.
From Chicago, the cheapest market for all carriers for next July has been Dublin--as low as in the $500's all through fall from Chicago. You can see if you can get el-cheapo add-ons from either
www.skyscanner.com or
www.ryanair.com If you connect to Dublin through AMS you will, of course, get another thousand miles!
