I’d like to take a suppressor with me on a hunt I have scheduled in Idaho. It’s legal in both states and I’ve got a direct flight. Good idea or bad? I’d keep a copy of the tax stamp in the rifle case, of course.

This is a good question. Personally, I wouldn't hesitate, but I'd also keep a digital copy of the stamp on your phone, or hard copy on your person too.

Great information at the below link, which you may have already read. But that doesn't replace experiences THF suppressor owners, who I'm sure will be along shortly.

Just posting for general FYI and future questions/searches. I'm sure each airline has their own procedures as well and it's best to check with them prior to each flight as regs may have changed since the last trip. https://www.silencershop.com/blog/post/traveling-with-a-suppressor

Just follow your airlines requirements (as well as the federal requirements related to interstate travel) and you should have no problem…

I’ll be taking a YHM Resonator K to Idaho in October myself (elk/deer combo hunt)… although I’ll be driving, not flying..

By federal law a suppressor is a firearm, so you have to treat it as such when flying.

You should be fine just putting it in the case with your firearm and declaring it like normal.

"Just like any firearm, you can fly to destinations where it is legal to bring your silencer. You’ll need to put your silencer in a TSA approved locking container and follow procedures for checking a firearm aboard the plane. Again, it doesn’t hurt to have copies of your paperwork with the silencer. Flying with a silencer is a fairly easy and painless procedure since it’s treated like any other firearm when checking it aboard the plane and clearing security."
