As a newbie I have just used one of my eVIPs to upgrade a JFK-LAX Flagship transcon from coach to business. In checking my reservation, I see the fare code now reads C instead of my original coach booking code. I thought an upgraded fare code would be R, or is this just the case for two-cabin planes? Is this correct, or did the agent by mistake put me into a full revenue C class? Also, noted that my fare went from $400 to $0 on the updated res. Is this normal too?
