Ceremonial Chocobo Can't Fly...? Really..?

which could be fixed by code not letting them on the chocobo if they are in an area currently not unlocked.

Yeah, and the code already exists in-game, you cannot use the wedding rings to teleport if one person has not unlocked flying in that specific zone, which was likely done to avoid these risks.

I personally believe they'll only make the Amber Draught Chocobo will be 2-sit flyable to get more people recruited into the game.
