Asthma? Airplane? Have developed asthma?

Around 2.5 yrs back, i was in a room for 90 min with 15 agarbati burning, After around 1 hr I started feeling chest pain and itching in nose, I had no idea it was due to agarbati, then i had shortness of breath and then i came outside the room and for several days i had chest pain, difficulty in breathing, itching in nose. I don't have Asthma And since then, I immediately feel shortness of breath, chest pain if i get in contact with smoke, agarbati, mortein, All out or any other smoke and I have to immediately go away from there, I can't take it anymore. And when that incident happened i went on to see a pulmonogist, he prescribed some medicine but i think as time passed i felt automatically better. He didn't said I developed asthma. Now my question is that Did i have developed asthma? They are only triggers otherwise i am absolutely normal. I am about to take a flight and i am worried if there are any trigger present inside the airplane, what will i do high in the sky. please Help.
