Dear all,

I hope I'm posting in the correct forum area, please correct me if otherwise.
I was looking to know how intra-EU IATA unrestricted fares are computed. I don't work in the travel industry and have just gathered that such information does not seem to be publicly available and that indeed selling seems to be a profitable business. I looked into www.passengerairtariff.com but the info. there is not the most exhaustive.

If anybody could give me a hint on how those are computed I would be most interested. I would be looking in particular at the city pairs LIS or OPO and PAR/LON/BRU.

Thanks in advance!
best
