Be prepared to get spoiled like you can't even imagine. CX crews just cannot do enough for you... the service level can be a bit disconcerting at first but there's nothing they won't do (within reason of course) for you. Also, the sleep suits are VERY comfy. I saw several westerners who looked at them as though they were alien artifacts and left them unused... don't make that mistake. If you like 'em, the FAs will most likely only be too happy to give you an extra if they're not too full.
