My husband has mostly 3 piece travel rods that he brings (fly rods) but he has brought other travel rods with for reef fishing. He packs all the stuff with hooks and extra line in the checked luggage and carrys on the reels and the rods. We have never had a problem in Belize - we have run into problems in other countries with the reels and the line - in Costa Rica they made him take the line off all his reels and throw it away before he could board the plane. He also sometimes brings down gear he is not going to use any more and gives it to local kids or guides before we leave.
