Ladies and gentlemen, a PSA from your humble editor..
Please check your firearms at the door while traveling.
You cannot fly while carrying a firearm or with one in your accessible carry-on baggage.
According to the TSA, in 2018, a record-setting 4,239 firearms were discovered in carry-on bags across the country.
Firearms must be unloaded and locked in a hard-sided container and transported as checked baggage only.
Firearms parts, including firearm frames and receivers, are prohibited in all carry-on baggage and must also be placed in checked baggage. – YourErie.com
Use a lockable case like in the title image and check your firearms under the plane using the process for the airline you are flying with.
