Thoughts on the Air Seychelles portion of the trip:
-Wine was selection of of South African Red, French Red, or South African White. The French Red ran out about half way through dinner.
-Dinner was choice of Beef, Chicken, or fish. Chose the chicken and it was edible.
-Seats were somewhat uncomfortable compared to DL's Business Elite product. They were cradle seats, but my seat didn't function properly as the foot rest didn't extend all the way.
-Funky spray was sprayed upon departure, they said it was compliant with international standards but I covered my mouth.

Thoughts on Air France portion of trip:
-Seats were more comfortable than Air Seychelles but not as good as DL's in my opion. I kept sliding down when it was fully reclined into the flat angled position.
-Food was pretty good. Although the service was lacking, basically they dropped off the food, gave 1 drink service, then disapeared as stated in other posts about AF.

The DL portions were fantastic.
-Food was on par if not a little better than AF's in my opion.
-The wine selection was comparable.
-I like the DL cradle seat the best compared to the AF & Air Seychelles seats.
-The FA's were by far the best on DL. Very friendly and genuinly made an effort to ensure we had a pleasant flight experience.

Hope this helps.
