In a study done by British Airways, read the article here, they claim that the most popular economy seats (on a 747) are those in the back. The reason they say they are are the most popular is because there are only 2 seats to the row and they don't have to share the row with a stranger. These are not my favorite seats at all! I prefer to sit as close to the front as possible, I want to get off that plane ASAP! Usually to catch another flight.
