Do we know if this 777-200 refurb schedule is on track? very limited info online. Booked JNB-CDG-JFK in june based on timings in premium. Was excited to fly the 77W and A350.

Both flights swapped to a 777-200 which is fine, but would prefer the new seats. Were thinking about spending an extra hour in CDG to fly Delta on the last leg to guarantee a better seat.
