They would probably interrogate you but the worst thing they would/could do is just take it.
Yes but no lighter
There is no age limit in the US to have a lighter in your possession.
From my experience, I was able to carry a Bic lighter with me in my check in baggage.
MOST people do not have a girlfriend at age twelve. Of course it is ok. It is normal.
No, I'm....ermm, at my age I forget how old I am, but I'm definitely not twelve.
No.
Yes, you can bring an electric lighter on a plane in your carry-on luggage, but not in your checked baggage.
Not in the US.
Laws on carrying lighters vary by location, but in many places it is not illegal for someone under the age of 18 to possess a lighter. However, purchasing lighters may have age restrictions depending on local laws.
i did it however it might get taken from you when you go through the carry-on luggage scan
