UA from beijing to Tokyo (UA) then from Tokyo to Dallas (AA) directly.the reason we selected this line is because my mom can get through Custom from Dallas directly and no need to pick up the heavy suitcases in the middle way. Also the Custom officer is really nice and not very strict.they didn't check her suitcases so now I already got some delicious food.. we bought ticket in Beijing, round trip price is about 7200 Yuan.she will be back at the end of Jan 2004.
hope it helps..
