I brought about 10 lighters home as gifts 2 weeks ago. I had several in 2 checked bags, a few in my carry on and at least 1 in my purse. My checked bags were opened apparently as I had Delta zip ties on the zippers of my checked baggage. I thought my lighters may have been confiscated but they were all there. They used to ask if anybody had lighters in the security line but they haven't asked in a few years.
