Airline trivia. Guess right and have a chance to win swag!

Last month, I asked a tough trivia question. What was the first scheduled airline to ban smoking on flights between North America and Europe?

I received a couple of guesses, but neither was the one I was looking for. I realize this is a bit of a tough question, so I'll give you a big hint. 

This airline is neither based in the United States nor Europe. If you need a further hint, the answer is Googleable. 

Leave your guesses in the comments section. I'll randomly select one correct answer and send you this Frontier Airlines lanyard. Perfect for any collection!
