There are certain food that you need to avoid to prevent dangerous gas interrupting your neighbour.
For example, leave the cheese offering out, broccoli, and any dairy products. I do have more stories...

1. Once on the previous lie-flat J, I was sleeping on the side and butt facing the passenger beside me. While turning around I accidentally released some gas right at his face. Good though he was sleeping.

2. On another flight, I got up to release gas. While walking towards the back of the plane, I just couldn't hold it anymore and let go while I was walking. Most of you may know the "drag effect". Which meant while I was walking, I was dragging my gas with me, so basically everyone sitting on the aisle......

OK, planes always have this "airplane smell". Is this what it is? Fart vapour saturated on the seat cushion for a long period of time.
