Small long haul network, not a big UE network and no domestic flights, so probably not many people for connecting. And point to point trafic is probably not enough to keep good capacities.
Contrary to the first lockdown, Air France kept to operate all its domestic service. From Montpellier, Marseille, Brest, Nice, Toulouse, the airline has operated flights from Orly and Roissy. For others destinations, either from Roissy or Orly. Orly was closed during the 1st lockdown.
At Montpellier (i m talking about MPL because i have family there and i spend apart of my life in this region), Air France operated up to 4 flights a day from Paris iso 0 flight during the 1st lockdown.
On the long haul side, the airline has served all its Africans routes and most of its routes to USA, Asia and South America. Pax trafic was not probably high, but they were probably less "only cargo" flights.
However, CDG now we work only with 2 terminals (2F and 2E mainly used by Air France). 2A and 2C are closed since 01Dec2020. T3, 2D and T1 are closed since spring 2020.
