Just for reference, both of the last two times we were at Amanpulo we caught the morning flight from the island to Manila, 10:40 arrival, and departed 12:50 from Manila to TPE. Both times we had lots of time in the airport to enjoy the wonderful *A lounge in Manila. Yes, that's a joke. The lounge sucks. But we did have 45 minutes or more after clearing security and customs until boarding.
