Just booked two business class AF tix on Delta.com: JFK- CDG, stopover, CDG-SEZ, SEZ-CDG, evening layover, CDG-JFK over July 4th week for 120,000 and $250 in taxes each. Price on AF.com for exact itinerary for both tickets was $31,017, bringing the total value of each Skymile to nearly 13 cents .. great value IMO

In order to book AF on DL.COM on multi-city search, I used Expertflyer.com 3 day flex search for O (Business class award availability). Surprisingly there was a lot. Once I had dates/ flight numbers, I plugged away on DL.com and it came up without a problem. Am very much looking forward to this trip- hopefully I can switch to the A380 flights if availability becomes open (set an Expert Flyer alert).
