Tips for 40 min Connections
Follow the yellow 'Transfer' signage immediately upon deplaning to reach the dedicated transfer security screening, bypassing arrivals immigration entirely.
If your connection is at the Midfield Concourse, budget extra time for the APM ride plus a long walk on either end.
Cathay Pacific's hub operation means many long-haul flights arrive and depart within the same 90-minute banks, so gates can be a considerable walk apart even within one concourse.
Use the free WiFi and abundant lounges (The Wing, The Pier) if you have a long layover, as Cathay's network is built for exactly this kind of connection.
Check your boarding pass for the gate area code (Main, North Satellite, or Midfield) before you deplane, since misjudging the distance is the most common reason for missed HKG connections.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
The Automated People Mover (APM) train links the Main Concourse to the Midfield Concourse and North Satellite Concourse in a few minutes, but long walks to and from APM stations add significant time. Transit passengers on through-checked itineraries usually pass only a transfer security screening (no immigration), though some itineraries require a walk of 15-20 minutes just to reach the correct pier before any train ride.
