I've invited my mother to join us on our France trip this May. She will be flying by herself from LAX to CDG on Air France and would like to fly business class (Affaires). Restricted round-trip tickets are currently about $5200. Does business class ever go on sale, or is that about the best fare that will be available?
I've checked various dates throughout the year, and the fares seem to be the same for all dates -- even though the AirFrance site indicates that there is currently a winter sale on business class.
Since I have never priced business class fares, I'm wondering if someone who has can give any advice on whether to buy now or whether historically there are any better fare sales on these seats in January-February.
