It looks like there are several options for travel rods, I would recommend that a four piece rod that is less than 20 inches per section so it can fit in a carry-on bag or a small backpack. Any rod should be carried in a protective case.

If one does not come with a case, PVC pipe of various diameters can be used.

I have a three inch diameter tube that carries an 8 WT fly rod, a light telescopic spinning rod and my two Fenglas rods that Gregg's converted for me.

Most of the time I check the tube in checked baggage since I am also checking my knives, lures, which aren't allowed in carry-on luggage.

I would recommend having one travel rod capable of handling lures up to
2 OZ. for jigging. My converted Fenglas rods handle these well.
