Cause base on the diagrams I have drawn, it looks impossible to access to T1 T2 T3 while transiting in T4 via early check-in.
The T4 setup is just like Hong Kong International Airport where Arrivals and Departures are segregated, and arriving passengers with connecting flights will have their boarding passes checked before entering the departure area.
This also explains why there is no signage to access to T1 T2 T3 - That path opening is meant for arriving passengers with connecting flights coming up from the arrival level via the escalator / lifts.
I ended up chose to fly Singapore Airlines instead of Cathay Pacific because of this - T4 just feels isolated for early-bird passengers like myself

(Already booked my SQ flights for my Hong Kong Disneyland trip next year)
Hi Amxmodx,
Not escorted as such, just pointed in the right direction. All the staff were quite open about it - nobody said "no" at any point. The route you have drawn is correct. There are several guard posts along the way and they point you in the direction of the next one. The lifts are there to take you down (the escalator only goes up). I actually walked through the arrivals hall to get to the waiting area.
I had an email from CAG today to confirm that this is a viable option and the route is approved. They have also sent a reminder to see the information desk on your way out to get the purple T4 re-entry sticker
The reason for the lack of signage is likely because it's quite a distance between terminals and may end up in passengers missing their flights.
Hope that helps!
