I had a 65 minute transfer just yesterday and it was enough time for me to clear security and go into The Pier for a bowl of warm noodles. However, I was nervous the entire flight into HKG because any slight delays or if my gates were located far away would stretch my connection time. Fortunately for me, my flight arrived on time and my arrival gate was gate 65 and my connecting flight was nearby at gate 61. Also, I was one of the first to deplane thus I was at the front of the security line. Unfortunately for me however, my luggage wasn't able to make my connecting flight even with the business class priority tags. The odd thing was that the luggage of my officemate who took the same flight as I did saw his luggage make the connecting flight even though he didn't have the priority luggage tags.

Personally, I won't be doing an itinerary again with such a tight connection time just for my peace of mind.
