On which airline can i smoke a cigarette?

I'm traveling from Bakersfield, California to Arlington, Virginia from West to east coast in just a few weeks. I have to know which airline to pick. I can't go more than 1 hour without smoking a cigarette. Gum and patches don't do it for me, I've tried. I need to smoke the actual cigarette. If I don't smoke I could start shaking and won't be able to sleep or enjoy my flight. I've been smoking cigarettes since I was 14. Now in my late 50's…

Please tell me which airline I can choose from. And also if no airlines allow smoking cigarettes, which is the most likely to consider allowing me to smoke a few cigarettes during my flight if I explain my need to them?

Thanks

Added (1). Never had to get on a plane before so didn't know it's illegal.

What is a deadhead and what does s/he do?

A dead head is an airline crew member, a pilot or a cabin crew, who is assigned to fly to a particular destination to assume a duty. In the flight where he or she is in, she's not supposed to work as a crew. He or she shall be in a complete uniform, thus making him or her able to sit on a jumpseat if the flight is full. Deadheading crew are also paid based on their flying time.

But I don't understand. What exactly does s/he do? Nothing? Just sit on the plane? Why are they paid then? What is the said 'to assume a duty'? So the airline company pays them to fly to a particular destination to do something there? Can someone explain please

Traveling through JFK airport with a firearm in my checked baggage?

I'm flying out of JFK with a handgun in my checked bag, or at least I think I will once I hear y'all responses. I have heard horror stories about people getting arrested at the airport for not having a NYC permit. I DO NOT have an NYC permit, I live in PA and have my PA and FL Permit, only traveling through JFK airport, not staying in NYC. Does anyone have any expertise or experience doing this.
