Few things
First check with your airline what limitaions you are under, check sporting eqipment. Some only allow you up to 80" in total rod tube length and weight limit of 50 pounds per checked item.
I have this and it's called a Bazuka tube, it, adjustable and padded at both ends. When measured out for 80 Inches and the pin in the proper place for that setting it comes our to 79 inches. If you want to max it out at 80" just slide it forward to 80" and drill a new hole for the pin that comes with it. The tube can hold up 7-8 rods with out any problem. This will limit you to a 6' 6" rod.
Do not lock the tube, they will cut it off. Just see if you can get an extra pin so they can open up the end for a visual inspection.
I would suggest that you put your name,address and phone numer on it also plus make a small sign for the opening end that states FISHING RODS please hande carefully.
I would also suggest that you take off your reels and either pack them or put them in your carry on if they are expensive reels.
Tackle like leader material, knives, hooks can be palces in the Bazuka also to max out the weight.
DO NOT PUT HOOKS OR KNIVES, OR ANYTHING SHARP IN YOUR CARRY ON!! They will have to be packed in your checked items.
Check weight limatations on your checked items, each item is allowed up to 50 pounds. Some airlines will allow you up to 70 pounds per item but charge another $25 for the extra weight per item. Checked items for domestic flight usually allow 3 checked and 1 carry on per person, some only 2 for checked items so again check with your carrier.
Cabellas, Bass Pro and sometimes even Sports Authority will carry these tubes which run about 60 bucks but you will have it a life time.
We just went through the same problem on the Mag Bay trip.
