When I'd gone on long car rides with family for a vacation, I would usually read. I'd also oftentimes bring a notebook to do some writing in (and quickly stop trying that after getting annoyed by bumps in the road). Sometimes I'd play the gameboy. The first time I flew to Alaska in middle school, I think I was too terrified to do anything for a good chunk of that flight. Then I read stuff I'm pretty sure.
Ever since high school, my flights and long car trips have been with a lot of friends, and we'd usually just talk the entire trip and joke around.
I also flew once with this flight attendant
and she made awesome jokes throughout the entire flight. She was a lot funnier on my flight than in this video, I think.
