I just noticed that AF is not selling any first class from CDG to DXB from 17-09 until 29-09. Does anyone know why? Do they sometimes have a temporary schedule change or does AF have a lack of planes with a P cabin during this specific period?

This is quite anoying for me, as I booked a la premiere ticket for the 20th of september. I just noticed that they downgraded me to business (without any notification...) and am now looking for alternative options.
