I just boarded KL1416 in LYS now, just in case you fly from France, it seems that only surgical type masks are allowed (and not my washable mask I had on the way to come here). When I checked my bag in, a friendly AF agent told me that I needed to change my mask for a surgical type one, and fortunately I had a couple with me. Looks like it's mostly for AF operated flights though, KLM once on board seems fine With any type of masks. No lounge in LYS open, and they asked us to fill in a form in French and English which they haven't picked up. However, the gate staff started their announcement by saying that I was good to see passengers back and thanked us for travelling today. I also saw the flight attendants and some ground staff handling the Lufthansa cityline flight from and to MUC taking selfies together (they are parked next to us). Travel is slowly picking up...
