Hi Gary, the CFO have a dedicated desk at NAIA (all terminals)
Many folks in the same situation have organised to get their 'sticker' at the CFO airport desk which is located within the departure area.
The desk is open Sunday to Saturday from 5:00am to 12:00 midnight.
Please be aware that you MUST organise this with CFO beforehand so that they will have the desk manned at the agreed time and with all paperwork.
The seminar certificate will need to be presented.
Give CFO a call to get things arranged.
The CFO at NAIA tel no is 8795685
Hope it helps
