I flew out of Philly with a firearm on March 1 on American and they have a new process.
They now put a red tag on the outside of the bag and when you arrive at your destination the bag is held in the baggage office and you have to show ID to get your bag.
I sent in a complaint that they are outing those traveling with a firearm and actually making these bags a target for theft. (see recent article - http://www.guns.com/2017/03/03/airpo...-from-luggage/ )

ALso I cannot check in for the flight online or via the app - i have to check in at the counter - I can understand this as it forces you to declare the firearm on a return trip.

Time to be flying other airlines.....
