I will be returning to Alaska soon and have some questions on bringing my bow back with me on Alaska Airline. I have a hard case, all my broadheads are in a safe package. Everything is secure. I know I have to open my case and have it inspected at the airport. I have been told that I then can lock the case using a TSA approved lock. Where to I find these? Is it worthwhile? Any other recommendations??? Any input is appreciated.
