You know what should be in the faq, but isn't? What a Y-up is. I looked in the main FAQ and it's not there and nothing about it in the fare bucket question. I guess the AU fare class sounds like it, but I'm not sure. In addition I was checking out some flights last week that I might need for work and one of flights had a y-up icon on it, but it sounded like it's based off of elite level, but I'm not elite so I don't know why I would have been shown that.
