Good day, my family and i are going to hongkong on april 23 and staying for 5 days but, a family friend will be tagging along but he will just be transfering to a different airplane my question is . we are arriving 10 pm at hk airport his flight will be april 24 at 1;45 am meaning he has only 3 hours and 45 minutes left from arrival so i have to take him to the terminal 1 for his quatar airways flight to dubai. is it allowed at hongkong and how far is the arrival area to the departure area of the airport . the last time i went to hk was a olong time ago it was still kaitak airport so i am worried that the immigration may not allow him to go out to transfer from the arrival area to the departure what should we do ? please guide and help me on what to do thank you in advance
