looking around at fares (haven't yet decided to do expert flyer, but I'm sure I will soon), Europe fares in I class are around $2500 for february (well, pretty much for all times between now and february, and it's the IGOSALE fare class). when I was looking about 6 months ago, they were around $1700, even for flying in the middle of august. I have seen some posts showing them going down to as low as $1100. For those of you far better in the know than I am, how low can I expect to see these fares go, and when will they go down? for the same flights, economy fares are running around $750.

thanks for any opinions.
