I have flown with 25k in pistols. Document them when checking them and if lost file a claim. I also have $200,000 in firearm insurance as well so if lost, damaged, house fire, stolen ect its all covered. Flying to Vegas in 2 months with a Barrett M82A1. Stress gets high but not much else to do to get them there. You can track your bags in the airline apps too. At the airport right now, this is trip 50 since January on a plane. No issues. Have another Saturday, another the 3rd ect ect.
