Byron,
If your flights are on a boeing 737 or larger aircraft, there is a large compartment right in front of you as you enter the aircraft. It is used to hold
garment bags and will take a large fly pole case. However, do take the advise from Allen, above. The PVC tube is easy to handle in a car or pick-up or van.
The reals you will have to cary on in your "carry on luggage". The airport inspection might ask where you'r going fish'en, but they get this all the time.
Good fish'en
