I am soon going on a tour to the Philippines (Cebu) with a stop in Manila. There, I need to transfer from terminal 1 (which serves for international flights only) to terminal 3 (domestic flights only). The two flights in and out of Manila are booked on different airlines. According to my search on the internet, I could find out that one may either take a (yellow airport) taxi (for maximum 200 PHP) or use the "new" shuttle service of the airport.
I have only three hours to make the transfer and have to get my luggage and check in for the next flight. Which way should I do it, in order to make my connection?
