They didn't say that they would order the 767-400 but...they might if they decide to order more 767's to expand their widebody fleet. As far as I know they haven't ordered any.
Also, they have never said that they would change their livery. You keep saying that American will have a new livery soon but they never said they would do so. I think that the one they currently have is good, I know it dates form the early 1970's but still it looks good. I'm not gonna describe now what I would do to change the livery at American because I've been talking about it before but if you want to go over it again please let me know and I'll make you a special post just for that, I'll describe you in detail what I would do of it.
