Thanks for the reply

Agreed on O and X (maybe A for AF as well?) for using partners' miles on AF/KL metal.

For dynamic pricing awards, there is a long thread about it on the AF/KL board.

The understanding so far:
- New system seems to work for Economy and Premium Economy as we see a wide range of required miles depending on route and loads. AAA-CDG-BBB prices differently as CDG-BBB for instance.
- Lots of unrealistic (but real) amounts of required miles for Business class even though loads are lights (think 450k+ for one-way Europe-Asia). Some suggest the system is not ready yet. Why for Business only remains a mystery though.

In any case I am eager to see how ExpertFlyer will handle this.
