I was wondering if this could happen at all the airports and all the Chinese airlines? The other day we were sitting at ICN airport, and everyone was de-icing, Korean air, Asiana, Cathay, Thai, Singapore and of course there were delays for everyone. But I saw all the Chinese airlines taxi out, line up and off they go.

I think it has more to do with keeping your bonuses than airline not allowing deice. I wonder what would happen to your safety bonus when you crash and burn?
