Can you check a gun at Chicago airport?

Answer 1

No. The city of Chicago has a gun ban.

I disagree. See How_can_you_transport_a_gun_to_Illinois_if_you_are_a_non-resident

and relevant posts at http://sigforum.com/eve/forums/a/tpc/f/320601935/m/760101641/p/1

for reasons why.

I updated my post on another question: the last time I travelled to Illinois, I was told I couldn't bring a handgun into Chicago in any way, shape, form, or fashion, however, I spoke to someone over the phone, so I don't know if they knew what they were talking about.
