both boarding passes are given in TIA, ask her to keep them safe..

check the HK airport website for the 'gates' few hours before the flight leaves TIA and communicate it to her atleast the no..if possible..

shouldn't be any problem, had my sister and kids come the same flights few months back..said was easy.

DONT GIVE HER MAPS..it gets TRICKY for no reason..u never know..the world isnt' that simple to think simple anymore.
