And the fine print

for non-domestic business class fares only:
- for flights originating in France
- for flights to France originating in GVA, BRU, BSL and LUX; hopefully the AF-operated restriction does not apply to BRU or LUX !
For flights in Y, the EUR 120 amount quoted by
Goldorak applies to a round trip. And the discount is not a fixed amount. It is
up to EUR 120.
