I have a 30" rolling duffle & I put my 4 pc rods in the bottom of that along with my flies tools etc. I've carried longer rods in tubes & once they took the longer cases at the gate & put them in the planes belly, like they do with strollers etc.& they gave them to me when we deplaned. I've been all over the US & even to Chile with my gear & the only problem i ever had was at Newark NJ. I had a inflatable PFD with 2 cans of CO2 in my carry on & they wanted to take it until I showed them the copy of the list of allowable items that someone on THIS forum (thank you) said to bring along & they let me keep it. Other than that I have pins in my shoulder & wrist that sometimes trip the alarm & I have to take off my shirt & get wanded........
