I’ve been on FS jet journeys only and met some fellow travelers on the last trip who mentioned how much they disliked their Aman jet experience. I don’t know which itinerary but the main issue was with the jet and the smaller group size. The layout of the jet sort of forces more socializing than you may want and the small size of the group makes it more difficult to avoid certain fellow travelers if you feel you must. They experienced multiple glitches in some logistics as well. So their 1 Aman trip vs 6 so far with FS says a lot.
