IATA YY unrestricted fares

[ip202659]

Hello everybody,
I've been looking for a piece of information that is not publicly available, I thought maybe some of you would have easy access to it and could maybe provide it in which case I would be most thankful.

Case in point are IATA YY Unrestricted fares ex-BRU. I was looking to know what these amount to, to Portuguese airports (LIS and OPO).

If anybody could provide a hint on these I would be most grateful.

many thanks,
