I flew through Phila International to Arkansas last year.
The locking system on the case pictured will not pass.
You need a case that will accommodate TSA approved locks. The locks are cheap and readily available.
I bought a gun case from Harbor Freight. The airlines beat the heck out of it but the guns did arrive undamaged.

This... 100%

You can buy a 4 or 6 pack of padlocks all keyed alike for reasonable price.
Make sure bullets are packed correctly also.

It's a shame some of the horror stories about how peoples guns were treated. I flew out of Philly with three guns and the lady was joking and having a good ol time.

Does TSA even make locks or is the wording starting to get confusing? I'm guessing most are meaning TSA APPROVED locks. I use regular Master locks that are approved by TSA.
