On all my travels to Argentina I have taped the rods to the side of the suitcase and protected the protruding tip of the tubes. Once the suitcase is full I place the rod tubes along the suitcase and then secure them in place with thick selotape. I then tape protectors to the tops of the tubes and the bottoms to protect them against wear. When I arrive at the airport I get them wrapped again. I have done this now for 7 years carrying up to 5 rods without any issues. For long rods (10´ 3 piece rods) I lay them cross ways.
