I have 125k Delta Skypesos to eat up, so I'm looking at booking a trip to CDG in June 2016 (24 hours of Le Mans!!!). I'm wondering what carrier offers the better business class product. Since I'm somewhat flexible on dates I can book it via Virgin Atlantic with a connection at LHR, or direct via AF... or I can mix the two.

I'm intrigued by the Upper Class bar, and I've generally heard that VA's product is better, I LOVE Virgin America in the US, too bad they don't operate flights out of DTW.

I'd love to hear what people think regarding this. Any input is greatly appreciated!
