I always feel like CX flights have the stinkiest toilets, whether it be long/short haul, and the people always take the longest? I ALWAYS find myself waiting forever in line for a toilet. I don't find people taking forever in say... SQ or TG...
If this really does have to do with the seasoning, maybe there's a connection between CX's better tasting food (IMO, compared to other airlines) due to CX using more seasoning, and therefore more stinkiness?
