Dave,
Buy some schedule 90 plastic pipe of whatever diamter that will fit all the ords in. Also buy some foam to put in the pipe to keep the rods from breaking. This works great. I have transported several fly rods at a time this way on planes. Seal both ends with rubber and clamps that a plumber would use to temporarily close up a job with. You can get this all at a hardware or plumbing supply store Frank O'R
