Still about the same, but some new sites
Check out booking buddy.com. You can see some other websites that I never saw before.I just got an price of 800 bucks (give or take) from GRB to TXL. Nothing great yet. But it lets you search all kinds of sites. It was kind of neat. I am hoping to run across super cheap flights about $500 bucks or so.
I priced a flight from Berlin to London for 4 days, It was about $230 USD. It would be nice if we could find a flight to Berlin OR London and visit a few days in each. At least in London, I can find out if we could stay with Kate. That would save some $. It looks like the flying/ travel time can be about 14 hrs. So the extra couple of days might be nice.
It was a bit less expensive to fly to London from Green bay ($30), but it is an option.

I used the dates of October 11 to 21st.
