On the shorthaul legs, though, there's not much value in J: CDG-HAM will be a cold, but plated meal (options being take it or leave it) and maybe fromage-its. HAM-AMS might have been downgraded to the new short-short KL service which is a snack bag and maybe a beverage service. Both will be Euro business: economy seats (maybe with Comfort+/Economy Comfort/Seat+ legroom) and on A220/A320/737, you'll have the neighboring seat blocked (on the Embraers, AFKL don't block neighboring seats in J, though AF does block the aisle seat on the left (2-seat) side of the A220).
