I cannot help either posters with AF flights mentioned on this topic with what will happen, or might happen.
I am not clear, OP how you booked your tickets. Did you use a travel agent of any kind? Did you book the Thai and AF legs on one, airline website, whether TG or AF? Or are each of the flights you mention entirely separate bookings, made by yourself on the airline websites, each time?
The easyJet flight - for the moment - is unaffected and a separate issue.
If the MEL to CGD via BKK two flight reservation was made under a single booking on AF's website, then when you reach BKK, AF have a EU regulated duty of care responsibility for you. How that will work, I don't know enough to make any suggestions. If it was all booked on TG's website, then it's possible that TG may route you on a different airline (if there are any) to fly you on the BKK to CGD leg, if the AF flight is not operating. That may involve further stops, of course and may not be the same day as seat availability issues may have relevance, and you won't be the only person in BKK wanting to get to CDG on AF.
However, the real reason I posted on this topic is to suggest, if you've not already done so, is to go and read and also post on the Paris destination forum.
The AF strike (and there may also be ATC ones) on 23 March is part of a 2 day strike, and France is in the throes of a wave of strikes affecting all sorts of other forms of transport at the moment and for the next few months. There are some very detailed, helpful threads on that forum (mostly concerned with the trains) but also with responses to other travellers affected by other methods of transport.
