Copenhagen-Paris 16th May. 2024 on a A320. Checked in on-line but to no avail, as luggage has to be checked in anyway. Check in refused to transfer my luggage to the next leg of journey, which was extremely inconvenient for transit in Paris and costed me at least an hour of extra struggle. Previously, AF in CPH often checked in my luggage to final destination. However, this service is obviously unpredictable, depending on who sits at the counter. The station manager tried and even took over the checking in. However, eventually she declined as she failed to identify any AF agreement with the concerned (next) airline: Rwandair. Boarding smooth, full flight; on time; luggage arrived well in Paris. Onboard, given emergency seat, fast track. Given access to “Apartment lounge” in Copenhagen due to FB status. This lounge is not worldclass, but is nowadays likely the best in CPH airport concerning food and drinks. Onboard, no free WiFi and no IFE. FAs were good and provided two rounds of cold sandwiches and most sorts of drinks. Wines were acceptable. Respected by FAs as Flying Blue gold card holder and I was well catered for. Could have rated much higher if they would have accepted checking in my luggage beyond Paris.
