The thing that I'd immediately wonder there is how "international trip" is calculated. It seems most probable that that number is calculated as "number of flights x people per flight". That would however lead to immense inflation. For instance you go on a round trip that involves 2 lay overs both ways, that'd be 6 "international trips." Do that once a quarter and a single person is taking 24 "international trips" in a year.
