We took a plane from Manila to Nagoya, Japan, then to Detroit, Michigan, then we split up and flew to our home cities.  The total in-the-air flight time back home (not counting layovers, delays, and ground time) was over 22 hours. Total round trip in-the-air flight time was almost 44 hours.  It took us approximately 80 hours total travel time to get to Mindanao and back.
