It's easy,you have to have a proper aircraft case with combinations,full length hinge and key locks. Inform your airline,we flew with Singapore air. At the airport this end they will open it in an interview room,only took 10 mins then when you and again they will open and take them until your licence is granted. You can only carry one gun person person so we took one each,me and hubby but in the same case. Pm for more info.
