My cousin booked a Star Alliance RTW ticket and is flying back to MEL from the US on UA. Oh dear! If only he knew how bad! I told him to fly back with NZ via AKL but I don't think he can change his ticket. On top of that he didn't sign up to earn miles before his first flight out of Oz but I made sure he did that when he got to London. Oooh! The frustration!!!
