On occasion, I will spend a day on a plane, doing a mileage run or just doing what I like best - flying. Yesterday I did a rdu-dca-bna-dca-rdu run, lasting almost nine hours. Not through any advanced planning on my part, I spent the entire day on the same plane (N822AE), an Embraer 140, which was a really good thing since we were running late all day, and I would have missed most of my connections. The trip entailed four different flight numbers, three different crews, two seats (8A and 9A) - I love the single seat on the Embraer - and one plane. It was a beautiful day for flying - crystal clear - although a bit windy. Anyone else ever spend a day on a plane just flying around?
