Do pay attention! Point 2 and Point 3 are talking about two different things. Apart from the $100 transportation fee from your home to the Airport (point 3), u have to pay a few hundreds more for her transportation from the Airport of her native place to her home. In my case, my agent satold me that I have to pay $350 (Airport of native place to her home) + air ticket + $100 (your home to the Airport in H.K.
I really don't know why she needs $100 to go from my home to the Airport? And also, I have no information on how much it should cost from the AIrport of her native place to her home?
