Hard landing and messy approaches in Japan and JFK?
That's what QR get when the instructors are kept away from flying to these destination.
Most TRI's / TRE's are in the sim, or flying to the ME and the Indian destination, then after 3 months of not visiting a special area and/or airport.....the instructor is rostered with a trainee who never flew in that region before !!
Improve the instructors rosters, you will have the numbers, then you can solve the training issues.
Suggestion: Allow the instructors to fly as "line captains" for a period of time, say 2 or 3 months per year, let them explore the fleet network.
That will make instructors get familiar with the destinations they never see, or rarely visit.
