I see this on many of the cheap-fare mailing list this afternoon. I try booking a week's trip to Quito or Lima for a week out of NYC, ORD, CLE and the cheapest I found was ~$240usd. At this price level, and having to get at least 1 positioning flight ($100 or more), it is not worth the hassle, especially when there are quite regular deals to Quito throughout the last year for under $300 from different airports.
