I finally found those flights, but after calling AY they told me that they can ´t help me with the booking since the hotline can´t book Business campaign fares - so no voucher use.

Whoooot?

Must have been a rookie Yan-Nih-Ka , did you try HUACA....

Maybe janica is using the enhaced finnair webpage to book flights... :)

That must be one of tve crappiest answers in a long time. Finnair agents are not able to access publicly published fares?

Could there be a currency problem—since an itinerary originating WAW would normally be priced in PLN whereas the voucher would be in EUR? I imagine a Finnair agent should be able to convert PLN into EUR and price the ticket in EUR, but I could see there being some difficulty.

Not related to points but qualifying segment, if flying HEL-CDG on AY metal, does the segment count towards AY plus even if ticket might be from AF or similar codeshare, but flight in any case the AY metal with AY code.

This is a recurrent question and the answer is always the same: AF-by-AY credits to Flying Blue, not to Oneworld programs.

You will get priorities and Platinum drink, but not lounge access.
