If you typically fly with Delta, you’ll want to keep an eye on the news. It appears that they’ve made some changes to their policies regarding the handling of checked firearms (which may or may not be legal changes, by the way). You can read more at this article from Ammoland:
Last week on these pages I wrote about an emailer’s experience flying on Delta airlines out of Norfolk, VA to St. Louis with a checked firearm.
It seems he had been given some information he had never heard before, and the process was different than he had experienced in the past. He was told his bag would be zip-tied before he could pick it up at his destination. Not only was he told it would be zip-tied, but it would also not be on the baggage carousel with every other regular bag. While the bag was not zip-tied, it did have a large “CAGPT” sticker slapped on it.
“CAGPT,” otherwise known in Delta circles stands for “Check and Give Protection to” and below the letters, it states, ‘Do Not Place on Baggage Carousel Belt.” This is the label usually affixed to bags containing high-value or fragile items. He was also told it was their new procedure for checked firearms.
