On my way to Cebu City last week, I came to see for the first time NAIA Terminal 3.
It is has a large check in area for Cebu Pacific and some Air Philippines flights.

There are numerous check-in counters in the lobby of the domestic flights side that cater to the travelers of the two airlines.
Each side of the check-in area has guide lines for the passenger queue.
After traversing the queue and paying for your terminal fee, you are going to face the long walk to the farthest gate - which is the gate given to us bound for Cebu.
There is, of course, a travelator for the passengers. The bad thing is that it only takes you through about 25 meters of the way to the farthest gate.
Fortunately for us, no ceiling collapsed at the time we were there. It collapsed on the day we were to return. :)
