Hi,
the carrier operating that flight is G3.
I fail to understand why you believe that there is no refund due, even if it's not under EU 261. Air France sold me a Business Class ticket. It's an AF flight number. It's not a Y fare basis. I travel in Economy. How is that not a downgrade? Should I perhaps initiate a dispute with the Credit Card Company (on the grounds the product/service which I purchased was not delivered - ie. Business Class seat on POA-GIG). Or even sue Air France here in Germany...?
This is how the flight is sold. Even if you try to buy a flight now on Air France's website, it sells as Business and there is no information on this specific flight being on Eco:
