I think something weird happened to my post. I can't seem to get it to show up. I got a crazy business fare yesterday through this somehow. RDU -> CDG nonstop roundtrip for 2 adults came out to $5,032.92 (with flatbed seats) Cheapest I could find on ITA Matrix is: $9,843.52.
Fares were I and Z class, same as found on ITA Matrix.
