At 30.9. I was flying with JAT (now AirSerbia) codeshared flight to Paris. At that time they had flight to Rio (GIG) after that TAM was flying direct to Montevideo.
At checkin desk of AirSerbia they refused two baggage, they said it is because they're acquired from Etihad and they don't approve two baggage, so I had to take other baggage as hand baggage.
Also in lounge they also refused Skyteam Gold card, same reason, they are not connected to Airfrance any more. No problem I had Priority pass.
For next trip I've checked AirFrance too. Truth they fly to Montevideo from CDG with one "technical stop".
That stop is in EZE, and you continue flight from AEP. Also you have it on their site. Checked yesterday again. You must pickup your baggage, try to get on other airport on time and checkin luggage again. Been there, done that, on return
I try to connect Alitalia and Aireuropa flight now, and that I cannot. I have separate flights from BEG to MPX and other with Aireuropa from MPX to MVD. I just want pleasant flight with less stress then last time.
