If I want to go from A to B, and there happens an airplane also goes from A to B, which has an empty seat, can I ask to go with it? It's like having a free ride in a carpool, but with airplanes?
I know this is ridiculous, but it will be an rewarding experience to think of. I'll be able to learn a lot. I was once almost too late to board, and was transported to the plane by a staff car, not by regular bus. I guess that I could have broken many safety rules, but if I can safely go with that car instead of the regular route, I would do it again.
If yes, what kind of airplane I can travel with? I guess in a commercial plane, I am expected to pay the ticket, so there's no way for me to go? A cargo plane might not be designed for an untrained person, but I guess as long as I don't lose consciousness, then it's still considered safe? A jet fighter... sorry, never mind. If no, what reason would it be? Is it because of safety, liability, or something else?
I will have one luggage and one backpack with me. Obviously I won't pull the exit door when the plane in the middle of the air.
