Not of the type that I think you mean. The smallest I took was what they call a "puddle jumper (or hopper) flight". It was a small propeller plane with only two seats on each side. Such planes are used just for very short flights. The one I took was between Philadelphia and Baltimore, cities that are quite close to each other. I remember it was a very windy day so the turbulence was awful. The plane kept "dropping" again and again. The one flight attendant for the plane kept having to put her arms up on the overhead compartments to keep from flying towards the roof. It didn't scare me that much as I had been on flights that had several "drops".

What was the best trip you ever took?
