on my current, rtw, i am about to fly through hong kong for the FIFTH time, as i added three additional segments in asia. however, when i was booking i wanted to go from scl to asia, and i was not allowed because i would have to go back through the us. i also was not allowed to go back through asia from australia to europe, so i had to book a flight that was direct, even if does stop in asia for refueling.
once again, consistency abounds.
