Classic example of "cracking a nut with a sledge hammer". You don't need Monte Carlo to understand that boarding first rows is less efficient, or to come up with a much more efficient procedure. (And this is coming from a Monte Carlo lover).
What you do need is biz savvyness to understand that rows are ordered by passenger value (first and biz class first, followed by premium, platinum, frequent flyers, etc). These passengers pay a high premium to board and deplane first. Airlines are not going to lose these valuable passengers for a gain whose magnitude is uncertain at best.
