Hi guys, I am traveling from Denver to Phoenix this summer to hike the Grand Canyon with my daughter and would like to bring a handgun with me. I am a licensed CCW holder in Colorado but have no idea what the airline regs are regarding transport of a handgun in checked luggage. Can anyone point me to where I can find out?

As long as it is checked I don't see a problem. Make sure it is unloaded. CCW should have nothing to do with it. However, you should check the regs in the Grand Canyon Park. I suspect that they do not allow firearms.

I suggest you check out Packing.org. There is all manner if info conserning packing a handgun around the nation.

thanks a lot guys - appreciate the info

Rock, as a generalization the firearm must be legal where you start and where you are to finish your flight. It is possible that if your plane was to be forced down in a unfriendly state that you could have trouble when changing planes and re-checking the luggage. A rare possibility. Normally a handgun is handled exactly like a rifle for air transport. Get information from your airline as well, as to their regs for packing. Go for it!
