I will use a DL Family & Friends Pass to NY on Aug 15.
* Do you know if I can use AF code-sharing flights with the pass? (3 daily AF CDG to JFK)
* May I use AF business class too?
* What is the probability I can get a seat on Aug 15?
* What margin should I keep to be back in Paris on Aug 28?
* How can I maximize my chances to get a seat?
* Who has any experience with this pass?
Thanx for your help!
