One of the Tutorial Activities that supports this book is an exercise in which the classroom is converted into an aircraft (with two rows of three seats with an aisle between), and students use different methods for boarding in order to investigate which is the most efficient. Students or Tutors that have done this exercise (or not) may be very interested to read this discussed in some detail on the Conversable Economist’s blog.
Two things emerge from his discussion. First, most models of boarding ignore the variety and complexity of passengers, assuming they are travelling alone with one carry on bag – in reality this is not the case. Second, airlines will continue to experiment with different boarding procedures, because in the U.S. alone, saving 2 minutes per plane would save $500 million a year from faster turn round times.
