Perhaps there is a better place to post this, but I haven't found it. I'm thinking of springing for Z fares in the summer. When I searched for them on ua.com, a bunch of CO flights popped up. As a longtime UA flier, should I try CO BusinessFirst? I like the new UA seats but I have to say the poor and disrespectful service is becoming old. I assume the miles will count toward lifetime status but, if not, I'd like to know.
