Indeed you are very lucky. After more than 40 sectors in 3 years this has never happened to me. Not that I mind, I use miles for the F experience and agree it is great. Though in my view CX or JAL are far better in seat/bed, crew and service food and wines.
At least Oeworld is together in product offerings. Sky Team should have a look at the wide variety of product offering. If you take a KLM flight it is misserable if you compare to AF.
