Things will absolutely escalate given how the gouvernement forced through the pension reform using 49.3 (aka ramming it thru by force).

Flights to/from CDG not too badly affected, if at all, but trains and public transits have been and will be more strongly perturbed. So plan for disruptions once you arrive. Depending on how long the blockages at the fuel refineries last, I fear that fuel may eventually be impacted too- bringing back bad memories of last october's fuel shortages.
