i arrive to T4 on cx and connect to AY flight from T1 on same day but 7hr later. i am hoping that bags get checked thru at hk but preparing for all contiengency. if my bags do get checked to final destination, but without boarding pass for AY flight on seperate PNR (is it even possible bags get loaded without boarding pass?) can i do airside T4 to T1? what do i show? eticket? or bag check slips?
