YOU CANNOT COME OUT OF THE AIRPORT IF YOU ARE IN TRANSIT UNLESS THE FLIGHT HAS BEEN DELAYED BY MORE THAN 6 HOURS THAN THE USUAL TIME. IN SOME CASE, THEY WILL LET YOU OUT IF YOUR TRNSIT TIME IS MORE THAN 12 HOURS. AND FOR YOUR LUGGAGE, IT WILL BE AUTOMATICALLY TRANSFERRED TO THE FLIGHT TO KATHMANDU. YOU CAN CHOOSE TO LEAVE THE AIRPORT WITH INTENTION NOT TO RETURN, HOWEVER YOU CAN STILL COLLECT YOUR LUGGAGE FROM KATHMANDU AIRPORT ON YOUR ARRIVAL NEXT DAY BY DIFFERENT FLIGHT. BUT ALL THIS YOU ARE TAKING A GREAT RISK AS YOU KNOW THE STAFF AT KTM AIRPORT.
